Procedure

2-Hexyldecyl chloroformate was prepared by adding 2-hexyldecanol (540 g) during 3 hours to liquid phosgene (500 g) which was refluxing below a condenser cooled with a mixture of solid carbon dioxide and acetone. After addition was complete the mixture was stirred for 30 minutes, and excess phosgene was then allowed to evaporate into a scrubbing device charged with 20% aqueous sodium hydroxide. The last traces of phsogene were removed by bubbling nitrogen through the liquid product while it was heated to 120°.
