Acrylonitrile is used principally as a monomer to prepare polyacrylonitrile, a homopolymer, or several important copolymers, such as styrene-acrylonitrile (SAN), acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylate (ASA), and other synthetic rubbers such as acrylonitrile butadiene (NBR). Products. SAN combines the clarity and rigidity of polystyrene with the hardness, strength, and heat and solvent resistance of polyacrylonitrile.

Other pertinent literature is also presented, but is described in less detail than the key studies. Acrylonitrile is an organic compound with the formula CH2CHCN. SAN combines the clarity and rigidity of polystyrene with the hardness, strength, and heat and solvent resistance of polyacrylonitrile.

Sicherheitshinweise. Formerly part of DSM, we have more than 50 years of experience in the safe and reliable supply of acrylonitrile, hydrogen cyanide, acetonitrile and sodium cyanide. 0001094480 00000 n [5], Various green chemistry routes are being developed for the synthesis of acrylonitrile from renewable feedstocks, such as lignocellulosic biomass, glycerol (from biodiesel production), or glutamic acid (which can itself be produced from renewable feedstocks). For each catalytic experiment, approximately 500 mg of catalyst was loaded into the reactor tube and placed in-between two quartz wool plugs. Acetonitrile is the most commonly used organic mobile phase component due to its unique properties that set it apart from the other LC ... . 0000003660 00000 n The experiment, designed by Idol and performed by Evelyn Jonak in March, 1957, resulted in ammoxidation, a process that produced acrylonitrile in about 50 percent yield with acetonitrile and hydrogen cyanide as co-products. Hydrodimerization of acrylonitrile affords adiponitrile, used in the synthesis of certain nylons: Small amounts are also used as a fumigant.
