ABS resin (acrylonitrile-butadiene-styrene) is a widely used terpolymer that accounts for about 8 percent of the butadiene market.
This is actually a whole set of related types of reaction, many of which have their own special name. These reactions are very useful for making new chemicals
* The applicability of Cannizzaro reaction in organic synthesis is limited as the yield is not more than 55% for either acid or alcohol formed.
Manufacture of propylene glycol (CH 8 -CHOH-CH 7 OH) consumes about 85 percent of the propylene oxide produced. Like ethylene oxide, propylene oxide undergoes hydrolysis to yield the corresponding glycol. Propylene glycol is mainly used to make polyester resins, but it is also used in foods, pharmaceuticals, and cosmetics.
Ethylene glycol (HOCH 7 CH 7 OH) is a toxic dialcohol. Approximately half of what is produced is used as automobile coolant (antifreeze) most of the rest is used to make polyesters for products such as fabrics, rigid films, and bottles.
. Phenylglyoxal undergoes intermolecular cannizzaro reactio n by giving Mandelic acid (&alpha -hydroxyphenylacetic acid or 7-Hydroxy-7-phenylethanoic acid)
This is one of the first named reactions most chemistry courses mention, but it has a simple variation, described below.
C-9 Chemistry (Butanes, Butylenes, Butadiene). Maleic anhydride is the main chemical made from n -butane. A complex catalyst is used for the oxidation reaction. The major uses for maleic anhydride are the making of unsaturated polyester resins (by reaction with glycol and phthalic anhydride) and tetrahydrofuran (by hydrogenation).
"Although there have been several books devoted to Micro Reaction Technology over the past decade, there has not been a volume focussed on the needs of the organic chemist. This excellent new book fulfils that gap."

Industrial organic chemicals are those 655 or so organic compounds produced in the United States in quantities ranging from millions of pounds to billions of pounds per year. Most of them are derived from petroleum (oil) or natural gas. From organic compounds present in petroleum and natural gas are obtained an amazing variety of products that includes many kinds of plastics, synthetic fibers, elastomers, drugs, surface coatings, solvents, detergents, insecticides, herbicides, explosives, gasoline additives, and countless specialty chemicals.
