    • Novel phosphoric esters represented by the following general formula (I) ##STR1## wherein R.sub.1 represents a linear or branched alkyl or alkenyl group having 1 to 36 carbon atoms, or a phenyl group substituted with a linear or branched alkyl group having 1 to 15 carbon atoms, R.sub.2 represents an alkylene group having 2 to 3 carbon atoms, R.sub.3, R.sub.4 and R.sub.5 individually represent a hydrogen atom or a linear or branched alkyl group having 1 to 36 carbon atoms providing that any one of R.sub.3, R.sub.4 and R.sub.5 has 5 or more carbon atoms, and n is a number from 0 to 30 are obtained by reacting phosphoric esters of the following formula ##STR2## with amines at a high purity and in a high yield. The phosphoric esters (I) are excellent in the surface tension and foaming property, and give extremely low stimulus to the skin, so that they can be utilized in detergent compositions, cosmetic compositions, emulsifiers, dispersants, anti-static agents and the like.

    • A novel process for producing a phosphoric monoester which comprises reacting per 1 mole of a linear or branched, saturated or non-saturated aliphatic alcohol having from 8 to 36 carbon atoms, from 2 to 10 moles of a polyphosphoric acid at 100 to 116% concetration converted as orthophosphoric acid in (a) one or more solvents selected from the group consisting of linear or branched saturated aliphatic hydrocarbons having from 4 to 8 carbon atoms and saturated cycloaliphatic hydrocarbons having from 5 to 7 carbon atoms, then adding (b) a lower alcohol having from 1 to 4 carbon atoms and water to the reaction mixture, transferring the orthophosphoric acid to the lower alcohol-aqueous phase to separate it from the phosphoric monoester, and concentrating the thus recovered orthophosphoric acid for reuse. The process reaction proceeds smoothly, separation and purification can be carried out readily and very effectively and the recovered phosphoric acid can be re-used.
    • 一种制备磷酸单酯的新方法,其包括每1摩尔具有8至36个碳原子的直链或支链饱和或不饱和脂族醇,2至10摩尔多磷酸,浓度为100至116% 在(a)一种或多种选自具有4至8个碳原子的直链或支链饱和脂族烃和具有5至7个碳原子的饱和脂环族烃的溶剂中转化为正磷酸,然后加入(b)较低 将具有1至4个碳原子的醇和水反应到反应混合物中,将正磷酸转移到低级醇水相以将其与磷酸单酯分离,并将由此回收的正磷酸浓缩以便重新使用。 过程反应平稳进行,分离和纯化可以容易且非常有效地进行,回收的磷酸可以重复使用。
