Versuchsvorschrift

A mixture of 1.52 mol of 2-(2-chloroethoxy)-tetrahydro-2H-pyran, 93 g of sodium hydroxide reduced to a powder and 25 g of tetrabutylammonium monosulphate is stirred for 1 hour and then distilled at 50° C. and 20 torr. The distillate is then dried over sodium sulphate, allowing the expected product to be isolated.
