Abstract: PURPOSE:To obtain the subject compound in good efficiency by adding a small amount of lower alcohol to a specified liquid mixture and a solvent in an extractor for continuous extraction by counter-current contact with the solvent so as to demulsify the emulsion state. CONSTITUTION:When a mixed solution of a phosphoric acid ester salt [e.g. a salt containing a monoalkyl phosphoric acid ester of the formula (R is 8-36C alkyl or alkenyl) as a main component] and a nonionic compound (e.g. organic hydroxyl compound) is continuously brought into counter-current contact with 4-8C aliphatic hydrocarbon or 5-7C saturated alicyclic hydrocarbon (preferably n-pentane) using an extractor to extract the nonionic compound into the solvent and separate the nonionic compound, a 1-4C alcohol (preferably ethanol is added so that the lower alcohol concentration in the mixed solution may become an amount of 0.5-2 pts.wt. based on 1 pts.wt. water and 1-5wt.% based on 1 pts.wt. solvent) is fed from one or more places to carry out the extraction.

Abstract: PURPOSE:To easily obtain the subject compound having good color and odor by reacting a sugar with a higher alcohol and contacting the resultant reaction product for the production of alkyl glycoside and containing unreacted higher alcohol with a specific compound. CONSTITUTION:A sugar is made to react with a higher alcohol or a sugar is successively reacted with a lower alcohol and a higher alcohol to obtain a reaction product for the production of an alkyl glycoside and containing unreacted higher alcohol. The reaction product is brought into contact with a metal hydrogen complex compound of formula M(BH4)x (M is alkali metal, Ca, etc.; x is 1 when M is alkali metal, etc., and x is 2 when M is Ca, etc.) (preferably sodium borohydride) and the alkoxide and higher alcohol are separated by conventional process such as distillation to obtain the objective compound. The contact treatment with the metal hydrogen complex compound is preferably carried out at 20-80 deg.C for 0.5-2hr.
