摘要： A process is disclosed for the production of an alkyl glycoside excellent in hue, which comprises (1) reacting a sugar with alcohol to obtain an alkyl glycoside reaction product containing an unreacted higher alcohol, (2) reacting the resulting product with a metal/hydrogen complex represented by formula (I)M(BH.sub.4).sub.x (I)whereinM is an alkali metal, Ca, Zn, or (CH.sub.3).sub.4 N; and x is 1 when M is an alkali metal or (CH.sub.3).sub.4 N and x is 2 when M is Ca or Zn;(3) separating the resulting reaction mixture into the alkyl glycoside and the unreacted higher alcohol, and (4) decomposing the remaining metal/hydrogen complex with an acid.

摘要： A process for the production of an alkyl glycoside or an aqueous solution thereof is disclosed, comprising the steps of (1) reacting a sugar with alcohol to obtain an alkyl glycoside reaction product containing unreacted alcohol, (2) establishing a moving liquid film of the alkyl glycoside reaction product and (3) contacting the moving liquid film with steam or an inert gas at a temperature of from 50.degree. to 200.degree. C. The alkyl glycoside or aqueous solution thus obtained contains little unreacted alcohol and is excellent in hue and odor.

摘要： An organic hydroxyl compound is reacted with polyphosphoric acid under such conditions that the ratio, as defined by formula (1), has a value exceeding 3.2; and phosphorus pentaoxide is added to the reaction product thus obtained in such an amount that the ratio, as defined by formula (1), has a value in the range of from 2.8 to 3.2: ##EQU1## If necessary, the obtained reaction product is deodorized by the removal of the organic hydroxyl compound unreacted therefrom. The process does not give any product of high-viscous gel and therefore enables the industrially easy manufacture of a phosphoric monoester having an extremely high purity, a lowered orthophosphoric acid content, and a good odor.

摘要： A phosphoric ester salt of high purity is produced by converting a phosphoric ester in a mixture containing the phosphoric ester and one or more nonionic compounds into a phosphoric ester salt by using a basic compound, and extracting nonionic compounds from the above mixture by using a mixed solvent of aliphatic hydrocarbons or cycloaliphatic hydrocarbons, a lower alcohol and water.The above method is applicable to a non-crystalline phosphoric ester from which nonionic compounds cannot be removed by recystallization.The above obtained phosphoric ester salt of high purity can be used as it is or after condensation.
