This compound has unique chemical properties. The synthetic route is as follows. 2807-30-9
100 g of 2-n-propoxyethanol,0.1 g of dodecyltrimethylammonium chloride was addedIn a reaction vessel equipped with a reflux condenser,120 g of thionyl chloride (content 99.0%Sulfuryl chloride content of 0.1%) by adding constant pressure dropping funnel,Stirring, slow to the reaction container dropwise addition of thionyl chloride, the reaction process release sulfur dioxide and hydrogen chloride gas,The temperature of the reaction solution was maintained at 30 ¡À 5 C by controlling the dropwise addition of thionyl chloride.Dropping of sulfoxide is completed, turn on heating,The temperature was gradually raised to 90 C according to the reaction gas evolution rate,Until no gas release, continue to heat 2h get crude; Crude direct distillation purification,105.9 g of chloroethyl n-propyl ether was obtained,After testing, product chromatographic content of 99.51%The water content was 0.17% and the yield was 89.97%.
