Through experiments we found that within a certain range to reduce the amount of allyl alcohol had no effect on the yield of the products shown in Table 1. At the same time ,<a href="http://www.toryburchrevaflats.org" target="_blank" class="postlink">tory burch flats</a>, Table 1 shows : When diethylene glycol chloroformate with allyl alcohol molar ratio dropped from 1:1.8 to 1:1.7 . Product yields a decrease of 94. Therefore,<a href="http://www.ghdglaetteisens.com" target="_blank" class="postlink">GHD glätteisen</a>, control of the reactant molar ratio 1:1.8 to 2.0 in the more appropriate .

A fact reduced because the methods used diethylene glycol chloroformate and water contact time , reducing the degree of ester hydrolysis . Table 2 How the product weight on the yield of the average response time for the three Rotary lively as chloride , 253 * in the reaction process will directly affect the yield of hydrolysis increased . So we shortened the reaction time than the original half of reaction time on product yield level. The results showed that the yield 【 group I group than the 4.8 increase in production . Table 3 The results show that reducing the reaction time will help improve production. Table 3 of reaction time on yield.
