Isopropenyl esters and half isopropenyl ester-half carboxylic acid products are prepared by reacting at a temperature of about 150.degree.-160.degree. C. at maximum pressures of from about 400 to 1000 psi for about 10 to 20 hours in the presence of a suitable catalyst and in N-methyl-2-pyrrolidone, a saturated or unsaturated aliphatic or aromatic dicarboxylic acid with methylacetylene or with a gas containing a mixture of methylacetylene, allene and some inert short chain hydrocarbons.
异丙烯酯和半异丙烯酯-半羧酸产物是通过在约150度至160度的温度下,在最大压力约为400至1000 psi的条件下,在适当催化剂的存在下,在N-甲基-2-吡咯烷酮中,与甲基乙炔或含有甲基乙炔、戊二烯和一些惰性短链碳氢化合物混合气体反应制备的。
