This derivative in turn is hydrolyzed to methacrylic acid, or esterified to methyl methacrylate in one step. Another route to methacrylic acid starts with isobutylene, which obtainable by dehydration of tert-butanol. Isobutylene is oxidized sequentially to methacrolein and then methacrylic acid.
Recent progress has been made for (partially) ionized MAA by introducing a new rate law for propagation where electrostatic and non-electrostatic effects are explicitly considered. [7] In addition, the rate constant of propagation (kp) during free radical polymerization of methacrylic acid is dependent on the monomer concentration.
Acetone cyanohydrin is an intermediate en route to methyl methacrylate. [6] Treatment with sulfuric acid gives the sulfate ester of the methacrylamide, [clarification needed] methanolysis of which gives ammonium bisulfate and methyl methacrylate. [7] It is used as a surrogate in place of HCN, as illustrated by its use as a precursor to lithium ...
