Methyl acrylate also used in making vitamin B1.

Acrylic acid esters in water-based coating, in particular butyl acrylates, are replacing more an more solvent borne paints. Typical commodity esters of acrylic acid are methyl-, ethyl-, n-butyl- and 2-ethylhexyl (2EHA)- esters. The strongest growth rates are expected with 2EHA, followed by butyl acrylate, methyl acrylate and ethyl acrylate.

It is prepared by the esterification of methacrylamide sulfate with methanol.

The principal use of hydrogen cyanide is in the manufacturing of acrylates, synthetic fibers (as a starting material for nylon 66), plastics and cyanide salts, especially sodium cyanide to extract gold from ore.

MMA is the monomer to make polymethyl methacrylate (PMMA) used as a shatterproof replacement for glass.

(The reaction of acetone and hydrogen cyanide forms acetone cyanohydrin, which is further treated with sulfuric acid to produce methacrylamide sulfate).

AB - A route based on deaminohalogenation of serine is established to synthesize bromoinimers that can be homopolymerized to produce hyperbranched polyacrylates that are true architectural analogues of linear polyacrylates; that is, an ester group is attached to every other carbon along the polymer backbone, and each repeat unit contains a free ester side chain.

A free-base tetrabromoporphyrin, 15,20-tetrakis(4-(2-methyl-2-bromopropoxy)phenyl)-21H,23H-porphine (2), was synthesized in high yield (91%) by the esterification of 5,10,15,20-tetrakis(4-hydroxyphenyl)-21H, 23H-porphine (1) with 2-bromo-2-methylpropanoyl bromide. The free-base porphyrin (2) was demonstrated to be suitable as an initiator for atom transfer radical polymerization (ATRP) of methyl methacrylate giving porphyrin-core star-poly(methyl methacrylate) with conversions of up to 98% ((CuBr)-Br-I, N-(n-propyl)-2-pyridyl-methanimine, toluene, 90 degrees C). UV-vis spectroscopic analysis demonstrated that a degree of complexation of Cu(II) by the porphyrin core occurred during the polymerization. To avoid Cu(11) complexation, zinc(II) 10,15,20-tetrakis(4-(2-methyl-2-bromopropoxy)phenyl)-21H,23H-porphine (4) was synthesized from the free-base porphyrin (2) and employed as an initiator in the ATRP of MMA, giving the corresponding Zn porphyrin-core star-PMMA. The free-base porphyrin (2) was also employed as an initiator for the polymerization of styrene, methyl acrylate, butyl methacrylate, octadecyl acrylate and the copolymerization of isobutyl methacrylate (IBMA) and trifluoroethyl methacrylate (TFEMA), in all cases giving star polymers with conversions of 33-87%. Basic hydrolysis of a porphyrin-core star-polystyrene polymer cleaved the ester linkages about the porphyrin, liberating the individual polystyrene chains which had a number-average molecular weight approximately one-fourth that of the precursor star polymer and a narrow polydispersity index (M-w/M-n, = 1.15) thereby demonstrating efficient initiation from the porphyrin core. Palladium(II) 10,15,20-tetrakis(4-(2-methyl-2-bromopropoxy)phenyl)-21H,23H-porphine (3) was synthesized from the free-base porphyrin (2) and employed as an initiator in the ATRP of MMA but the polymerization was completely inhibited. Pd(II) was introduced into the star polymer cores by heating either a solution of the porphyrin-core star-PMMA or the Zn porphyrin-core star-PMMA with (PdCl2)-Cl-II in benzonitrile. Pt(II) was introduced into a star polymer core by heating a solution of the Zn porphyrin-core star-PMMA-co-TFEMA with (PtCl2)-Cl-II in benzonitrile. UV-vis spectroscopic analysis confirmed the synthesis of Pd(11) and Pt(II) porphyrin complexes and photoluminescent spectroscopy confirmed the luminescent properties of the materials
