ConditionsYieldWith tetrabutoxytitanium; 4-methoxy-phenol In o-xylene at 80 - 90℃; under 75.0075 Torr;Experimental ProcedureIn a 500 ml four-necked flask equipped with a distillation apparatus, a thermometer, and a stirrer,1,4-butanediol monoglycidyl ether (hereinafter referred to as "14 BDMGE"100.0 g (purity: 93.7%, 0.64 mol in terms of purity)),125.1 g (0.96 mol) of 2-methoxyethyl acrylate,200.0 g of o-xylene and 0.03 g of MEHQ were added to prepare a raw material mixture solution(Total 425.1 g) were prepared.When the moisture content of this raw material mixture liquid was measured with a Karl Fischer moisture meter, it was 503 ppm, and the total amount of moisture contained was 0.21 g (0.012 mol). To the above raw material mixture solution, 4.4 g (0.013 mol) of TBT was added,While heating the solution under reduced pressure while reducing the pressure to 100 hPa, transesterification reaction was carried out at a reaction solution temperature of 80 to 90 ° C. while o-xylene and produced 2-methoxyethanol were distilled out of the reaction system.The temperature of the distillation gas was 57 to 74 ° C.Finally, 169.9 g of the fraction was withdrawn in 6 hours and the reaction was terminated to obtain 255.2 g of a reaction solution containing 4 HBAGE (46.3 wt%).The purity-converted quantitative yield of 4 HBAGE is 92.0%, and the molar ratio of the total amount of moisture in this reaction system is 0.9 times the TBT used. To the above reaction solution, 140.0 g of water was added, heated to 60 ° C. under normal pressure with stirring, and heated and hydrolyzed at 60 ° C. for 1 hour as it was. The reaction solution was cooled and suction filtered using a filter equipped with Celite to remove insoluble catalyst. The filtrate was separated into an organic layer and an aqueous layer. The organic layer containing 4 HBAGE was concentrated under reduced pressure using a rotary evaporator to obtain 130.8 g of 4 HBAGE crude product (purity 94.0%). The purity-converted quantitative yield of 4 HBAGE was 95.8%, and the content of titanium derived from TBT used as a catalyst was 2 ppm or less.50.0 g of the above 4 HBAGE crude product (130.8 g) was fractionated, 0.08 g of CBC was added thereto, and purification was carried out by simple distillation under reduced pressure. As a result, high purity 4 HBAGE (purity 96.9%) was obtained.The purity-converted quantitative yield of 4 HBAGE is 83.7% in terms of the consistent yield from the transesterification reaction. Conditions at the time of fractional distillation were 0.4 to 0.6 hPa in the degree of vacuum, 103 to 114 ° C. in the bottom liquid temperature, 93 to 95 ° C. in the distillation gas temperature, about 1 hour in distillation time there were. No polymer was observed in the distillation residue and in the distillation system.83.7%
