摘要
A process for preparing a composition of alcoholic esters of straight chain monocarboxylic acids containing 6 to 26 carbon atoms and glycerin, starting from a vegetable or animal oil, neutral or acidic, virgin or recycled with mono-alcohols containing 1 to 18 atoms, in the presence of a zinc aluminate catalyst and in the presence of a controlled quantity of water, can directly produce, in one or more steps, an ester which can be used as a propellant or fuel along with glycerin having improved purity containing a reduced quantity of ethers by using a partially dried catalyst.
