Preparation method of neopentyl glycol dimethacrylate

The invention provides a preparation method of neopentyl glycol dimethacrylate. The preparation method comprises the steps that under the effect of a catalyst on methylbenzenesulfonic acid, in presence of a polymerization inhibitor and an azeotropic water-carrying agent, neopentyl glycol and methacrylic acid react with each other for 4-7 hours at 78-92 DEG C to synthesize neopentyl glycol dimethacrylate, wherein the mole ratio of methacrylic acid to neopentyl glycol is 2.15:1, the dosage of the azeotropic water-carrying agent n-hexane is 45% of the total mass of the reactants, the mass of thecatalyst is 4% of the total mass of the reactants, and the dosage of the polymerization inhibitor phenothiazine is 0.1% of the total mass of the reactants. The synthesis method of neopentyl glycol dimethacrylate is simple in process, high in yield and low in chromaticity, the adopted catalyst is low in price and high in stability, and the method has broad application prospects.

Hydroxy functional acrylate and methacrylate monomers prepared via lipase-catalyzed transacylation reactions

Candida antarctica lipase B (CAL-B, Novozyme 435) catalyzes the transacylation of methyl acrylate and methyl methacrylate with diols and triols in 2-methyl-2-butanol at 50 °C. Under the experimental conditions, up to 70 mol% of the acyl donor methyl acrylate was converted. Methyl methacrylate is the less efficient acyl donor (up to 60 mol%) due to the higher sterical hindrance in the enzymatic transacylation. Under the reaction conditions high yields of the mono-acylated products are obtained, which contain minor amounts of bis(meth)acrylates. In addition it was observed that Novozyme 435 catalyzes regioselectively the acylation of the primary hydroxyl groups. In comparison with the chemical catalyzed route no selectivity was observed for unsubstituted diols. For substituted diols more mono-acylated product was formed in the lipase-catalyzed reaction than in the chemical catalyzed reaction.

Process for synthesis of Di(meth)acrylic acid esters

A process for the synthesis and recovery of di(meth)acrylic acid esters at a high degree of purity. Di(meth)acrylic acid esters are produced by transesterfication of (meth)acrylic acid esters of C1to C4alcohols with 1,n-diols (where n≧3) in the presence of a zirconium catalyst that comprises a chelate of zirconium with a 1,3-dicarbonyl compound. These catalysts can be readily separated or removed from the reaction mixture by precipitation with phosphoric acid, thus providing a convenient and inexpensive method of producing a di(meth)acrylic acid ester with a reduced level of zirconium.
