Abstract
Isopropenyl esters are made by reacting methylacetylene with a saturated aliphatic acid containing 2-18 carbon atoms at 10-15 DEG C. in the presence of a catalyst comprising boron trifluoride etherate and mercuric oxide or a mercury salt of an aliphatic carboxylic acid. The boron trifluoride etherate is preferably used in association with the red form of mercuric oxide or with mercuric acetate. Analytical grade red mercuric oxide and freshly distilled boron trifluoride etherate are preferably used. A small proportion of an aliphatic alcohol, e.g. methanol, ethanol or propanol, may be included in the reaction mixture. Examples are given of the preparation of isopropenyl acetate and propionate. Other specified acids which may be esterified are isobutyric, valeric, caproic, heptoic and caprylic acids.
