Abstract: PURPOSE:To reduce the equipment cost by carrying out an aging reaction and partial removal of an unreacted higher alcohol at the same time and reducing load on a process for thorough distillation of the unreacted higher alcohol. CONSTITUTION:In production of an alkylglycoside using a sugar and a higher alcohol, the sugar is initially reacted with the higher alcohol in the presence of an acid catalyst. An aging reaction is then carried out using a thin membrane reactor, etc., and unreacted higher alcohol is simultaneously distilled off from the reaction mixture till 30-60wt.% concentration of the higher alcohol. The reaction is subsequently stopped by neutralizing the catalyst and the unreacted higher alcohol is then distilled off using a thin membrane evaporator, etc., to reduce the concentration of the higher alcohol to

Abstract: PURPOSE:To produce the subject compound at a low cost by directly reacting a sugar with a higher alcohol, etc., and treating the reaction product with a spontaneous liquid film evaporator, etc., while recycling the recovered unreacted higher alcohol to the alkylglycoside production process. CONSTITUTION:An alkylglycoside containing unreacted higher alcohol is produced by reacting a sugar with a higher alcohol or reacting a sugar with a lower alcohol and reacting the product with a higher alcohol. The reaction product is separated into recovered higher alcohol and a crude alkylglycoside containing 30-60wt.% of unreacted higher alcohol using a spontaneous liquid film evaporator. The alcohol is removed from the crude alkylglycoside with a forced thin film evaporator to obtain the objective compound containing

Abstract: PURPOSE:To readily and continuously obtain the subject compound with a high selectivity in a high yield while making the residence time short by carrying out a reaction between an aliphatic alcohol and polyphosphoric acid in a hydrocarbon-based solvent in a tubular reactor. CONSTITUTION:Using a tubular reactor, 8-36C chain aliphatic alcohol (e.g. octyl alcohol) is reacted with polyphosphoric acid in a hydrocarbon-based solvent (preferably cyclohexane, etc.) to obtain the objective compound. In addition, removal of heat of the reaction is preferably improved in the initial stage of the reaction using a multi-tubular reactor (d) and mixing and heat transfer in the reaction tube are preferably promoted in the initial stage of the reaction by equipping a static mixer in the flow path of the tubular reactor. As the direction of the liquid flow in the tubular reactor, rising flow or lowering flow is preferable.
