What is adiponitrile used for?
Adiponitrile (ADN) is used almost exclusively to make hexamethylene diamine (HMDA), of which 92% is used to make nylon 6,6 fibres and resins. Most ADN production is used captively.
How is adiponitrile produced?
Adiponitrile is a large scale chemical intermediate used in the production of Nylon 6,6. It is primarily produced via two methods: the thermal hydrocyanation of butadiene and the electrochemical hydrodimerization of acrylonitrile.
Where does adiponitrile come from?
butadiene
The majority of adiponitrile is prepared by the nickel-catalysed hydrocyanation of butadiene, as discovered at DuPont, pioneered by Drinkard.
What products does ascend make?

Which raw materials are used in nylon?
Raw materials used in nylon are petroleum,natural gas,lime stone, coal,water,acetylene etc. polyster is made using purified terephthalic acid and monoethelyne glycol etc. >>
Is butadiene a monomer?
Polybutadiene [butadiene rubber BR] is a synthetic rubber. Polybutadiene rubber is a polymer formed from the polymerization of the monomer 1,3-butadiene. Polybutadiene has a high resistance to wear and is used especially in the manufacture of tires, which consumes about 70% of the production.

How do you make chloroprene?
Chloroprene is produced in three steps from 1,3-butadiene: (i) chlorination, (ii) isomerization of part of the product stream, and (iii) dehydrochlorination of 3,4-dichlorobut-1-ene.
