Preparation of Diethylene glycol monobutyl ether: it can be prepared by butanol and ethyl ether boron trifluoride. This reaction will need reagent epoxyethane. The reaction time is 2-3 hours at reaction temperature of 75-80 °C. After the reaction, use butanol sodium to make pH into 8, then put it into the distillation tower for distillation.
Uses of Diethylene glycol monobutyl ether: it can be used as solvent of nitrocellulose, varnish, printing ink, the oil ans the resin. It also can be used for adhesive thinner and emulsioni paint stabilizer. In addition, it can react with (2-methoxy-phenoxy)-acetyl chloride to get Butoxyethoxyethyl o-methoxyphenoxyacetate. This reaction will need reagent CHCl3. The reaction time is 21 hours by heating. The yield is about 69.01%.
