Abstract

A 20 mmole quantity of methyl‐^13^C fluoride at a ^13^C‐enrichment level of 90% was prepared by a two‐step synthesis starting with methanol‐^13^C. The overall yield was 60% of methanol used. A series of gas‐chromatographic treatments using Ascarite, silica gel, and Chromosorb‐102 columns yielded a highly purified methyl fluoride in which the major impurities were less than 10 parts per million of carbon dioxide and 10 parts per million of methyl chloride.
