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.
Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate is significantly less volatile than simpler phenolic antioxidants such as butylhydroxytoluene (BHT). This makes it more suitable to stabilising plastics, as it is not driven out by the high temperatures experienced during plastic extrusion and moulding, [2] when they are heated to 150-320 °C (300–600 °F).

Butyl cyanoacrylate has been used to treat arteriovenous malformations [6] by application of the glue into the abnormality through angiography. In gastroenterology, butyl cyanoacrylate is used to treat bleeding gastric varices , which are dilated veins that occur in the setting of liver cirrhosis or thrombosis of the splenic vein . [ 7 ]
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 .
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
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.
Dow Inc. remained in the Dow Jones Industrial Average, which technically gave DuPont (via the split) a continuous presence in the index since 1935. This officially comes to an end today.
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.
