    摘要： A process for the production of fatty acid esters comprising; (a) subjecting a fatty acid or fatty acid mixture to esterification with a lower alkanol in an esterification reactor maintained under esterification conditions to form a stream comprising the corresponding lower alkyl ester or esters and recovering same; (b) recovering an overhead stream from the esterification reactor comprising unreacted lower alkanol, water, and a heavy organic content comprising one or more of lower alkyl ester and/or acids; (c) subjecting the recovered overhead stream to distillation in a first distillation column operating under first distillation conditions to separate a portion of the lower alkanol from a stream comprising the water, the remaining lower alkanol and the heavy organic content; (d) recovering the stream comprising the water, the remaining lower alkanol and the heavy organic content; and (e) subjecting the stream comprising the water, the remaining lower alkanol and the heavy organic content to distillation in a second distillation column operating under second distillation conditions to provide an overhead stream comprising lower alkanol and at least a major portion of the heavy organic content and a water stream having a reduced heavy organic and alkanol content.

    摘要： A process for the production of fatty alcohol or alcohols comprising: subjecting a fatty acid or fatty acid mixture to esterification with a lower alkanol in an esterification reactor maintained under esterification conditions to form a stream comprising the corresponding lower alkyl fatty acid ester or esters; vaporising the stream from step (a): subjecting the vaporised stream of step (b) to hydrogenation in a first hydrogenation zone operated under hydrogenation conditions to form a stream comprising fatty alcohol or alcohols and an amount of unconverted lower alkyl fatty acid ester or esters; subjecting the stream from step (c) to transestenfication in a wax ester reactor maintained under transestenfication conditions in the presence of a transesterification catalyst thereby to convert at least a portion of the lower alkyi fatty acid ester or esters by ester interchange with a corresponding amount of fatty alcohol or alcohols to lower alkanol and to a wax ester or esters; separating the stream from step (d) by distillation to yield a fatty alcohol or alcohols product steam; a wax ester or esters stream; and an overhead stream comprising fatty a!kanol or alkano!s and alkane, and optionally one or both of water and lower alkanol; reacting said overhead stream from step (e) in a wax ester reactor maintained under transestenfication conditions in the presence of a transesterification catalyst with a lower alkyl fatty acid ester or esters thereby to convert at least a portion of the lower alkyl fatty acid ester by ester interchange with a corresponding amount of fatty alcohol or alcohols to lower alkanol and to a wax ester or esters; and separating the wax ester or esters formed from the alkane, and any water and/or lower alkanol present.

    摘要： A process for the production of propylene glycol from a lactate ester is disclosed. The process comprises supplying a feed comprising a C3-6 alkyl lactate ester. The feed is contacted with a stream of hydrogen containing gas and subjected to hydrogenation in the vapour phase in the presence of a catalyst at a temperature of from about 130° C. to about 185° C., a pressure of from about 20 bar to about 60 bar, and a weight hourly space velocity greater than about 0.3 h−1. The catalyst is a reduced copper catalyst selected from copper alumina, optionally comprising manganese, copper chromite, copper zinc oxide and Raney copper.
