Abstract: PROBLEM TO BE SOLVED: To provide an evaporation method of a foamable solution capable sufficiently suppressing both of thermal foaming and mechanical foaming, with a high treatment efficiency of the foamable solution per unit volume of an evaporator.
SOLUTION: This evaporation method of the foamable solution uses the evaporator having a foamable solution introducing port and a vapor taking-out port at the upper part of the evaporator. The superheated foamable solution is introduced into the evaporator from the introducing port, formed into a vapor-liquid mixture and jetted to a coolable wall face of the vapor phase of the evaporator, allowed to flow down on the wall face, and cooled below a boiling point at an operation pressure until reaching a liquid sump part of the evaporator.

Abstract: PROBLEM TO BE SOLVED: To efficiently obtain a low irritative and highly foamable cationic surfactant having a high quality. SOLUTION: This method for producing the cationic surfactant comprises reacting an amine with cationizing agents of formula I (R2 -R4 are each a 1-3C alkyl; Y is H, hydroxy; A is OH, a halogen, a 1-4C alkyl sulfate; Z is a halogen; n is 0-5) and/or formula II. Therein, an aqueous solution (hereinafter referred to as a cationizing agent solution) containing the cationizing agents of formula I or/and formula II and controlled to a pH of 7-11 is changed into a device for forming a thin film, and the formed thin film of the cationizing agent solution is subjected to the removal of volatile components. The formed dried cationized agents are used as the above-mentioned cationizing agents. The reaction is performed at room temperature to 150 deg.C as such or under vacuum, while steam or an inactive gas is blown into the cationizing agent solution. The production method can avoid the thermal deterioration of the cationic surfactant, efficiently remove the volatile components generating irritative orders in the easy operation, and give the objective high quality compound not causing the deterioration of the smell even with time.

Abstract: PURPOSE:To advantageously obtain an aldehyde of high quality by efficiently and simply separating a specific aliphatic alcohol and the aforementioned aldehyde prepared from the alcohol according to dehydrogenation thereof with pseudo-moving beds using a specific adsorbent without requiring heating at high temperatures. CONSTITUTION:Both (A) an average 10-30C straight-chain/branched chain saturated/ unsaturated aliphatic alcohol and (B) an aliphatic aldehyde obtained by dehydrogenating the alcohol (A) are separated from a raw material mixture containing both to produce the aliphatic aldehyde (B). In the process, packed columns (C1) to (C12) filled with silica gel are connected in series in a liquid passage in an endless form and eluate feed ports (a), taking outlets (b) for the solution (A), raw material mixture solution feed ports (c) and taking outlets (d) for the purified liquid (B) are arranged in the above-mentioned order along the flow of the solution at a prescribed interval. Pseudo-moving beds intermittently and successively moving the ports (a) to (d) to the downstream side are used as an adsorber to bring the adsorbent into apparent countercurrent contact with the eluate and enable continuous operation. Thereby, treating efficiency is remarkably raised and the amounts of the adsorbent and the eluate are simultaneously reduced to advantageously afford the aldehyde (B) of high quality.

CONSTITUTION:A plurality of feeding columns C1-C12 filled with an adsorbent adsorbing selectively specified components are connected in series in a liquid path, and a first filled column and a last filled column are connected together in the liquid path to form up an endless line. In the filled column group, elution raw material feeding ports (a), specified component feed-out ports (b), raw material feeding ports (c) and feed-out ports (d) for other components are disposed along the liquid flow direction in this order at the given interval, and ports (a)-(d) are moved intermittently to the downstream side successively. At least either one of specified component feed-out flow rate or the flow rate of other components is made smaller than the raw liquid feeding flow, and also adsorption properties in the elution liquid in the solvent composition is made smaller than the adsorption properties of raw liquid to the specified component or other components.

Abstract: PURPOSE: To obtain a high-quality, low-irritant/highly foamable surfactant by removing volatiles, etc., through the use of a thin film, from a crude reaction liquor containing a cationic surfactant made by reaction of a specific cyclic amine and/or amidoamine with a cationizing agent. CONSTITUTION: Firstly, a reaction liquor containing a cationic surfactant of formula IV (E is H, a 1-3C alkyl, etc.) is obtained by reaction of (A) a cyclic amine of formula I (R1 is a straight chain or branched chain 7-15C alkyl or alkenyl; G is H, a 1-3C alkyl or hydroxyalkyl; m is 2 or 3) and/or an amidoamine of formula II (G1 and G2 are each H, a 1-3C alkyl or hydroxyalkyl, however, at least one of them being H) with (B) a cationizing agent of formula III (R2 -R4 are each a 1-3C alkyl; Y is H or hydroxyl; A is OH, a halogen, etc.; Z is a halogen; n is an integer of 0 or 1-5, however, when n is 1, Y is H or hydroxyl, when n is 0 or 2-5, Y is H). The reaction liquor is then continuously fed into a device provided with a thin film and allowed to flow thin-film-fashion to remove the volatiles contained in the liquor, thus affording the objective cationic surfactant.

Abstract: PURPOSE:To obtain a sulfobetaine good in solubility in bleaching and washing and further preservation stability by crystallizing the sulfobetaine from a polar solvent, separating the sulfobetaine, then adding a surfactant to the resultant sulfobetaine containing the polar solvent and subsequently drying the sulfobetaine. CONSTITUTION:An omega-halogenated fatty acid ester of phenolsulfonic acid expressed by formula I [R is alkyl; X is halogen) is made to react with an amine expressed by formula II (R is alkyl, alkenyl, etc.; R and R are alkyl; Y is alkylene, etc.; m is 0 or 1] in a polar solvent to provide a mixture or the compound expressed by formula I is allowed to react with the compound expressed by formula II and the polar solvent is added to the resultant reactional product to afford a mixture. A sulfobetaine of formula III is crystallized and separated from the prepared mixture. A surfactant is then added to the sulfobetaine containing the polar solvent and the obtained sulfobetaine is subsequently dried to afford the objective sulfobetaine. An anionic surfactant is preferred as the surfactant and, among them, a sodium alkylbenzenesulfonate or sodium alkyl sulfate is preferred. The sulfobetaine is useful as a bleaching activator in an oxygen-based bleaching agent.

Abstract: PURPOSE:To enable economical production of the title compound having good color and smell through simple operations by reaction of an polyhydric alcohol with an alkyl glycidyl ether in the presence of a catalyst followed by neutralization, decolorization and deodorization treatments of the reaction mixture. CONSTITUTION:The reaction of a polyhydric alcohol such as pentaerythritol with an alkyl glycidyl ether such as isostearyl glycidyl ether is carried out in the presence of an acidic or basic catalyst such as sodium hydroxide in a solvent such as dimethyl sulfoxide, as they are heated at 105 deg.C for 4 hours. Then, a neutralizer such as acetic acid is added to the reaction mixture to give a mixed solution containing glyceryl-etherified polyhydric alcohol, which is subjected to decolorization treatment using an oxidizing agent such as 35% hydrogen peroxide and/or subjected to deodorizing treatment using steam, nitrogen or an inert gas whereby the objective glyceryl-etherified polyhydric alcohol of good hue and smell is economically and simply obtained.
