Distribution Agency


Distribution is the process of moving product from business (manufacturer/producer) to the end user. This intermediary role is played by distributors who collect production from the manufacturer and ensure its availability to the end user.

Investment in a small or medium scale distribution business would largely depend on the following factors:  Distribution territory or region to be covered,  Population of the area,  Number of houses; and  Family size.
The entrepreneurs choose locations like bungalows in the vicinity of the industrial areas or godowns within the industrial arras. Proximity of distribution house to the target market plays major role to cut down ransportation cost and increase revenue. Besides, loading and unloading of goods would be convenient.

Distribution business is a logistics business which draws a considerable investment in the
goods transportation vehicles. Success of the business largely depends on the efficient
transportation and delivery of products.

  • Benzidine is prepared in a two step process from nitrobenzene. First, the nitrobenzene is converted to 1,2-diphenylhydrazine, usually using iron powder as the reducing agent. Treatment of this hydrazine with mineral acids induces a rearrangement reaction to 4,4'-benzidine. Smaller amounts of other isomers are also formed. The benzidine rearrangement, which proceeds intramolecularly, is a classic mechanistic puzzle in organic chemistry.
  • Benzidine - based dyes are largely classified as direct dyes, since they may be applied directly to fabrics or other substrates without pre-treatment or without subsequent processes that firmly attach the dye to the substrate.



Linalool




  • Linalool is a colorless to very pale yellow liquid with a floral smell similar to that of bergamot oil and French lavender. It is a naturally occurring substance that is used to make fragrances and flavors.

Silver Nitrate


Silver nitrate is an inorganic compound with chemical formula AgNO3. This compound is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides. It was once called lunar caustic because silver was called luna by the ancient alchemists, because they believed that silver was associated with the moon.

Silver nitrate can be prepared by reacting silver, such as a silver bullion or silver foil, with nitric acid
Silver nitrate is the least expensive salt of silver; it offers several other advantages as well. It is non-hygroscopic, in contrast to silver fluoroborate and silver perchlorate. It is relatively stable to light. Finally, it dissolves in numerous solvents, including water.

Silver nitrate is used in many ways in organic synthesis, e.g. for deprotection and oxidations. Ag+ binds alkenes reversibly, and silver nitrate has been used to separate mixtures of alkenes by selective absorption. The resulting adduct can be decomposed with ammonia to release the free alkene.

banana fibre extraction

Pyrogallol


  • Pyrogallol or benzene-1,2,3-triol is a benzenetriol. It is a white crystalline powder and a powerful reducing agent. It was first prepared by Scheele 1786 by heating gallic acid. An alternate preparation is heating para-chlorophenoldisulphonic acid with potassium hydroxide.
  • When in alkaline solution, it absorbs oxygen from the air, turning purple from a colourless solution. It can be used in this way to calculate the amount of oxygen in air, notably via the use of the Orsat apparatus.
  • One can find its uses in hair dying, dying of suturing materials and for oxygen absorption in gas analysis. It also has antiseptic properties. Pyrogallol was also used as a developing agent in black-and-white developers, but its use is largely historical except for special purpose applications.

Food irradiation


Food irradiation is the process of exposing food to ionizing radiation to destroy microorganisms, bacteria, viruses, or insects that might be present in the food. Further applications include sprout inhibition, delay of ripening, increase of juice yield, and improvement of re-hydration.

The commercialization of food irradiation is increasing. Retail stores that offer irradiated products for sale are experiencing positive consumer responses.

The cost of food irradiation is influenced by dose requirements, the food's tolerance of radiation, handling conditions, i.e., packaging and stacking requirements, construction costs, financing arrangements, and other variables particular to the situation.

Polypeptides



Polypeptides are chains of amino acids. Proteins are made up of one or more polypeptide molecules.
A polypeptide is a long, continuous, and unbranched peptide. Proteins consist of one or more polypeptides arranged in a biologically functional way and are often bound to cofactors, or other proteins.
The utilisation of peptide synthesis technology in solving health problems of worldwide importance was mainly dictated by the desire to obtain stable products devoid of the various contaminants often seen in recombinant material (glycosylation variants, proteases, DNA, endotoxins) in record time and in reasonable quantities to perform preclinical testing.

Polyimide



Polyimide is a polymeric plastic material, engineered for long term performance at very high temperatures, in excess of 250° C for prolonged periods of time.
Polyimide is made from two key ingredients, which may each contain traces of impurities, such as water vapor, or even traces of iron from the chemical drums containing solvents used.
Major producers of polyimide film, Kaneka High Tech Materials(KHM) (Manufacturing facilities in Texas and Japan) and Dupont have reacted to this situation and have announced plans to significantly increase capacity sometime during the first half of 2002.
Consumption of polyimide and other imide polymer resins in Asian countries other than Japan, including China, India, the Republic of Korea, Malaysia and Taiwan, has been growing rapidly in recent years despite the global economic recession

Cast Nylon




Cast nylons are a range of polyamides produced by a casting process involving the anionic polymerisation of caprolactam.
The family of nylons consists of several different types. Nylon 6/6, nylon 6, nylon 6/10, nylon 6/12, nylon 11, nylon 12, and nylon 6-6/6 copolymer are the most common.
Cast nylons are used in a wide range of applications, from a simple equipment support pad, to a sophisticated drum in a machine that sorts thousands of coins a minute, to a sheave on a crane that can lift 1,000 tons, to a component used to eviscerate chickens! There is perhaps no other process that can produce parts weighing from one pound to over eight hundred pounds in tooling that, relatively speaking, costs peanuts.
China’s demand for nylon 6 driving it, caprolactam pricing in Asia moved upward dramatically during Q1 and the attractive pricing is pulling in material from the world.
Asia nylon 6 and 6,6 markets inched upward in March. The spot nylon 6 price for Chinese and Taiwanese brands stabilized, while US$ imported nylon 6 price were strong.

Polybutylene




Polybutylene (polybutene-1, poly(1-butene), PB-1) is a polyolefin or saturated polymer with the chemical formula (C4H8)n.
Polybutylene is a form of plastic resin that was used extensively in the manufacture of water supply piping from 1978 until 1995. Due to the low cost of the material and ease of installation, polybutylene piping systems were viewed as "the pipe of the future" and were used as a substitute for traditional copper piping.
Polybutene consumption is most influenced by the market for fuel and oil additives, which in turn, is a function of lubricant sales. Lubricant sales in the US are growing at slightly better than 1%/year.

Foliage Plants

Foliage plants are grown mainly for their leaves. Due to the fact that most foliage plants are tropical in nature, they adapt easily to indoor conditions.

As foliage plants are produced primarily for interior decoration or interior plantscaping, new end use will generate greater demand in production. New cultivar releases and new plant introductions provide products for new uses, and desire for novelty and new uses among consumers promote selection of new cultivars and introduction of new plants, which then increase production.
