Reaktionsschritte

Boron trifluoride was introduced with vigorous refluxing (bath temperature 50° C.) into a mixture of 138 g (1 mole) of 2,3-dimethylhydroquinone, 370 g (1.62 moles) of myristic acid and 700 ml of methylene chloride until saturation. After standing overnight the reaction mixture was decomposed by pouring into 3 l of a 10% by weight sodium acetate solution with stirring. The methylene chloride was evaporated by means of steam. The residual oily layer solidified after cooling to a melt cake that was isolated by decantation. It was melted up and added with stirring to 2 l of high-boiling benzine. The precipitate was filtered with suction and washed with benzine (boiling range: 50°-75° C.). After being dried the precipitate was stirred with acetonitrile and filtered with suction.
