Yield:7098-80-8 64%
Reaction Conditions:
with sodium carbonate
Steps:
R.4 (Preparation of ketal group-containing monomer)
Referential Example 4 (Preparation of ketal group-containing monomer) Into the apparatus for monomer synthesis were charged 2,2-dimethyl-1,3-dioxolan-4-methanol (DMDOMeOH), toluene, triethylamine (equimols to DMLOMeOH) and phenothiazine (2% of DMDOMeOH) and the mixture was stirred at room temperature. Methacrylic anhydride (90 mol% of DMDOMeOH) was dropped into the mixture at room temperature, then the reaction was continued at 110°C for 10 hours. The reaction mixture was extracted with hexane, neutralized with an aqueous solution of sodium carbonate, and dried over anhydrous sodium sulfate. After addition of phenothiazine (2% of DMDOMeOH), the extract was concentrated under reduced pressure at 80°C. The crude product was subjected to vacuum distillation using Vigoureux column to give 2,2-dimethyl-1,3-dioxolane-4-yl-methyl methacrylate in a yield of 64% based on charged DMDOMeOH. The product having a boiling point of 52-53°C at 0.45 mmHg is hereinafter called methacrylic acid ester (B-4).
