摘要： This invention provides a process for producing esters of fatty acids and one or more polyhydric alcohols comprising the steps of:
(a) providing a reaction mixture comprising free fatty acids and one or more polyhydric alcohols;
(b) heating said reaction mixture to a temperature at which said free fatty acids react with said one or more polyhydric alcohols ; and
(c) subjecting said reaction mixture to a flashing step generating a vapour stream and a flashing residue comprising said esters.摘要翻译： 本发明提供一种生产脂肪酸和一种或多种多元醇的酯的方法，包括以下步骤：（a）提供包含游离脂肪酸和一种或多种多元醇的反应混合物; （b）将所述反应混合物加热至所述游离脂肪酸与所述一种或多种多元醇反应的温度; 和（c）使所述反应混合物经历产生蒸气流的闪蒸步骤和包含所述酯的闪蒸残余物。

摘要： The invention provides a continuous process for removing organic solvents from a marc comprising the steps of:
a) continuously introducing said marc into a desolventiser;
b) introducing an inert, gaseous stripping medium into said desolventiser;
c) removing said organic solvents from said marc by maintaining a subatmospheric pressure inside said desolventiser, thus providing an organic solvent-desolventised material; and
d) continuously extracting said organic solvent-desolventised material from said desolventiser;
wherein step (a) and (d) comprise compacting said marc and said organic solvent-desolventised material into a plastic, substantially gas-impermeable mass and extruding said mass through an annular gap, the opening of which is controlled by the rate of supply of said plastic mass.
The invention also provides a device for compacting a moist organic material into a solid gas-impermeable mass which is useful for implementing this process.摘要翻译： 本发明提供了一种从马桶中除去有机溶剂的连续方法，包括以下步骤：a）连续将所述马克斯引入脱溶剂; b）将惰性气态汽提介质引入所述去溶剂中; c）通过在所述去溶剂中保持低于大气压的压力来从所述马桶中除去所述有机溶剂，由此提供有机溶剂脱溶剂材料; 和d）从所述去溶剂中连续提取所述有机溶剂脱溶剂材料; 其中步骤（a）和（d）包括将所述马克和所述有机溶剂脱溶剂材料压实成塑料的，基本上不透气的物质，并通过环形间隙挤出所述物料，所述环形间隙的开口由 说塑料块。 本发明还提供了一种用于将潮湿的有机材料压实成固体气体不可渗透的物质的装置，其对于实施该方法是有用的。
