Formic acid tert-butyl ester is a chemical compound from the group of carboxylic acid esters .

Extraction and presentation

Formic acid tert -butyl ester can be prepared by reaction of tert -butanol with formic acid in the presence of sulfuric acid are recovered. The compound is also formed when calcium formate is reacted with formic acid. It is one of the by-products of the breakdown of methyl tert-butyl ether (MTBE).

properties

Formic acid tert -butyl ester is a colorless liquid. In the environment the compound decomposes mainly by hydrolysis to tert -butyl alcohol and formic acid. The half-lives in aqueous solution are 6 hours at a pH value of 2 (at 4 ° C), 5 days at pH 7 (at 22 ° C) and 8 minutes at pH 11 (at 22 ° C).

use

Formic acid tert -butyl ester can be used in gasoline formulations.
