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).

For well over a century, the Dow Jones Industrial Average (DJINDICES: ^DJI) has served as a barometer that gauges the health of the U.S. stock market.. When the Dow Jones was officially incepted ...
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.
If it connects at one of the non-terminal (internal) carbon atoms, it is secondary butyl or sec-butyl: −CH(CH 3)−CH 2 −CH 3 (preferred IUPAC name: butan-2-yl) The second isomer of butane, isobutane, can also connect in two ways, giving rise to two additional groups:
Year to date, only 10 of the 30 Dow components are outperforming the S&P 500 at the time of this writing. And two of those components -- Nvidia and Amazon-- were added to the Dow this year ...
But the mother of all end-of-year market chaos moments happened in a 10-day stretch to end 2018, when the Dow sank 4,000 points before staging one of the best days on record — a 1,086-point gain ...
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 ...
