Styrene is an organic compound with the chemical formula C 6 H 5 CH=CH 2. Its structure consists of a vinyl group as substituent on benzene. Styrene is a colorless, oily liquid, although aged samples can appear yellowish. The compound evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor.
Most of those methods, but not all, involve the use of a solvent either for liquid-liquid extraction or extractive distillation. Many different solvents are suitable, including sulfolane (C 4 H 8 O 2 S), furfural (C 5 H 4 O 2 ), tetraethylene glycol (C 8 H 18 O 5 ), dimethylsulfoxide (C 2 H 6 OS), and N-methyl-2-pyrrolidone (C 5 H 9 NO).
d is the average particle size, k includes parameters related to the reaction vessel design, D v is the reaction vessel diameter, D s is the diameter of the stirrer, R is the volume ratio of the monomer to the liquid matrix, N is the stirring speed, ν m and ν l are the viscosity of the monomer phase and liquid matrix respectively, ε is the ...
Ethylbenzene is an organic compound with the formula C 6 H 5 CH 2 CH 3.It is a highly flammable, colorless liquid with an odor similar to that of gasoline.This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene, the precursor to polystyrene, a common plastic material.
The liquid within the chamber of an e-cigarette is heated to roughly 100-250 °C to create an aerosolized vapor. [4] This is thought to result in pyrolysis of the e-liquid and could also lead to decomposition of other liquid ingredients. [4] The aerosol (mist [5]) produced by an e-cigarette is commonly but inaccurately called vapor. [1]
ASA can be made by either a reaction process of all three monomers (styrene, acrylonitrile, acrylic ester) or a graft process, although the graft process is the typical method. A grafted acrylic ester elastomer is introduced during the copolymerization of styrene and acrylonitrile. The elastomer is introduced as a powder. [11]
AMS is formed as a by-product of the cumene process.In this procedure, cumene is converted to its radical, through a reaction with oxygen. Normally these cumene radicals are converted to cumene hydroperoxide, however they can also undergo radical disproportionation to form AMS.
It is a colorless liquid that is typically stored with a stabilizer to suppress polymerization. In combination with styrene, vinylbenzyl chloride is used as a comonomer in the production of chloromethylated polystyrene. [1] It is produced by the chlorination of vinyltoluene. Often vinyltoluene consists of a mixture of 3- and 4-vinyl isomers, in ...
