Butyl acrylate is of low acute toxicity with an LD 50 (rat) of 3143 mg/kg. [ 4 ] In rodent models, butyl acrylate is metabolized by carboxylesterase or reactions with glutathione ; this detoxification produces acrylic acid , butanol , and mercapturic acid waste, which are excreted.
2-Ethylhexyl acrylate is a colorless liquid acrylate used in the making of paints, [2] plastics [3] and adhesives. [4] It has an odor that has been variously described as pleasant [ 5 ] or acrid and musty.
tert-Butyl methacrylate is an organic compound with the formula (CH 3) 3 CO 2 CC(CH 3)=CH 2. A colorless solid, it is a common monomer for the preparation of meth acrylate polymers . [ 2 ] It is employed in other kinds of polymerizations .
Base catalysed Michael addition of methyl acrylate to 2,6-di-tert-butylphenol forms the intermediate butyl-phloretic ester. High temperature transesterification of this with pentaerythritol gives the final product. Driving this reaction to completion can be difficult and commercial samples often contain low levels of the tri-ester.
The acrylate ion is the anion CH 2 =CHCO − 2. Often, acrylate refers to esters of acrylic acid, the most common member being methyl acrylate. These acrylates contain vinyl groups. These compounds are of interest because they are bifunctional: the vinyl group is susceptible to polymerization and the carboxylate group carries myriad ...
In the 1960s, James A. Herbig and Ival O. Salyer of Monsanto were the first to attempt to make what would become ASA using butyl acrylate as the rubber phase. This work was then refined by Hans-Werner Otto and Hans Peter Siebel of BASF using a copolymer of butyl acrylate with butadiene for the rubber phase. [10]
Poly(butyl acrylate) (PBA) is a family of organic polymers with the formula (CH 2 CHCO 2 CH 2 CH 2 CH 2 CH 3) n. It is a synthetic acrylate polymer derived from butyl acrylate monomer. The polymers are colorless. This homopolymer is far less important than copolymers derived from methyl acrylate and other monomers.
Methyl acrylate can be prepared by debromination of methyl 2,3-dibromopropanoate with zinc. [10] Methyl acrylate is formed in good yield on pyrolysis of methyl lactate in the presence of ethenone (ketene). [11] Methyl lactate is a renewable "green chemical". Another patent [12] describes the dehydration of methyl lactate over zeolites.
