    Abstract: PURPOSE: To obtain a phosphoric monoester useful for detergents, textile treating agents, etc., in high purity and yield without converting the reactional product into a gelatinous material by reacting phosphorus pentoxide, etc., with an organic hydroxy compound under specific conditions. CONSTITUTION: The method for producing a phosphoric monoester is to react phosphorus pentoxide and polyphosphoric acid as phosphorylating agents with an organic hydroxy compound such as octanol under conditions so that a value represented by the formula may exceed 3.2, then add the phosphorus pentoxide to the resultant reactional product and carry out the reaction under conditions that the value, represented by the formula and based on the total amount of the polyphosphoric acid and the phosphorus pentoxide may be 2.8-3.2. Furthermore, the concentration of the polyphosphoric acid is preferably 105-120wt.% expressed in terms of orthophosphoric acid and the unreacted organic hydroxy compound is preferably removed from the reactional product containing the phosphoric monoester by the steam distillation to deodorize the reactional product.

    Abstract: PURPOSE:To simply and inexpensively prepare the subject high quality compound or an aqueous solution thereof by flowing a reaction product prepared by directly reacting a saccharide with a higher alcohol, etc., or an aqueous solution of the reaction product in a thin filmy state and subsequently bringing the thin-filmy reaction solution into contact with steam, etc., at a specific temperature. CONSTITUTION:A saccharide such as glucose, maltose or inulin is directly reacted with a higher alcohol of the formula (R is 6-22C alkyl, etc.; A is 2-4C alkylene; n is on the average 0-5), or the saccharide is reacted with a lower alcohol and subsequently with the higher alcohol. The unreacted alcohol contained in the reaction product used for the preparation of an alkylglycoside or an aqueous solution is reduced to 3-10wt.%. The reaction product or the aqueous solution thereof is flowed on a thin film evaporator in a thin film state of

    Abstract: PURPOSE:To obtain a compound having excellent color and odor and high quality at a low cost by preparing a reaction solution containing benzalkonium halide from dimethyl-t-amine and a benzyl halide and flowing the reaction solution in the form of a thin film in an inert gas or steam. CONSTITUTION:A solution containing benzalkonium halide of formula (R is 8-30C alkyl or alkenyl) is produced by reacting a dimethyl-t-amine with a benzyl halide. The solution is flowed in the form of a thin film in a flow of a gas inert to the benzalkonium halide or in a steam flow. The evaporation of unreacted benzyl halide is promoted, the odor is improved and a benzalkonium halide having high quality is produced by this process. The contact area of the solution with the steam or inert gas can be increased without causing the foaming of the solution and the effect of the treatment can be improved by flowing the solution in the form of a thin film. The benzalkonium halide is a cationic surfactant useful as a sterilizing agent, an antiseptic agent, a wound cleaning agent, etc. The process enables the production of the compound with easy operation in a short time.
