摘要： PURPOSE:To obtain the titled compound useful as an active component of detergent, etc., in high purity, by sulfonating an inner olefin, and adding a lower alcohol and optionally water to the reaction mixture to remove the unreacted olefin. CONSTITUTION:A 8-30C inner olefin is sulfonated with gaseous SO3, neutralized with an alkaline aqueous solution (e.g. sodium hydroxide solution), and hydrolyzed. At an arbitrary stage after the sulfonation process, a lower alcohol (e.g. methyl alcohol) or its mixture with water is added to the reaction mixture in an amount to give the concentration of the inner olefin sulfonic acid salt in the slurry of 2-30wt%, and the weight ratio of the lower alcohol to water of 2/8- 6/4. The unreacted olefin in the slurry is separated to the upper layer by the specific gravity difference. The layer containing the unreacted olefin is removed to obtain an inner olefinsulfonic acid salf free from unreacted olefin.

摘要： PURPOSE: To remove the unreacted oil componet from a slurry of an anionic surface active agent containing said oil component, in high efficiency, with small amount of steam, preventing the foaming of the slurry, by introducing steam continuously into the slurry under specific pressure to effect the gas-liquid contact, and releasing the steam to a low-pressure atmosphere.
CONSTITUTION: A slurry of an anionic surface active agent containing unreacted oil component, e.g. an aqueous slurry containing 10W50wt% of a surface active agent and containing 5W50wt%, based on the surface active agent, of unreacted oil component, is introduced into the pressure vessel 4 through the line 1. Saturated steam heated at 130W250°C is introduced continuously into the vessel 4 while keeping the pressure in the vessel at ≥5kg/cm
2 , preferably 7W50kg/cm
2 to effect the thorough contact of the gas and the liquid (for 5W30min.), and flushed into the cyclone-type gas-liquid separator 6 maintained to atmospheric pressure. The objective surface active agent slurry is obtained from the bottom 9 of the apparatus 6. The process is especially effective for the treatment of internal olefinsulfonic acid salt and paraffinsulfonic acid salt having poor reactivity for sulfonation and containing a large amount of unreacted oil component.

摘要： PURPOSE:To obtain high-quality sultone useful as a raw material for preparing a detergent, an antistatic agent, etc. simply and safely, and to use the remaining sulfonate effectively, by aging a reaction product obtained by sulfonating an olefin, adding a basic aqueous solution with a high concentration to it. CONSTITUTION:10-20C olefin is sulfonated, the reaction product is aged at 20- 150 deg.C (preferably at 40-80 deg.C), and a basic aqueous solution (e.g., >=40wt% aqueous solution of NaOH) with a high concentration is added to it, so that sultone is expelled from the micell of a sulfonate to the outside, separated as a continuous phase, and recovered by settled separation, centrifugation, filtration, etc. Since the remaining sulfonate can be recovered in a state nearly free from thermal decomposition, it is usable as an approximately pure anionic surface active agent with a high concentration. USE:A raw material for preparing a detergent, cosmetic, antistatic agent, auxiliary for fiber, etc.

摘要： PURPOSE:To produce the titled compound useful as a surface active agent such as detergent, etc., continuously, in high concentration, by neutralizing and hydrolyzing an olefin sulfonate with an alkali agent at a specific temperature so as to produce a specific amount of sultone, heating the reaction mixture, and again hydrolyzing the product. CONSTITUTION:An aqueous slurry of an olefinsulfonic acid salt is produced by neutralizing and hydrolyzing an olefin sulfonate. The reaction is carried out by neutralizing and hydrolyzing the olefin sulfonate with an alkali agent (e.g. hydroxide or oxide of alkali metal, such as NaOH, KOH, etc.) at 100-140 deg.C so as to attain the content of the water-insoluble sultone in the olefin sulfonate of 0.5-4wt% based on the olefinsulfonic acid salt, and then hydrolyzing again at 150-200 deg.C. The increase in the viscosity after the neutralization can be suppressed, and since additives are unnecessary in the process, the objective compound having high versatility can be produced at low cost without forming by- products.

摘要： PURPOSE:In starting the neutralization of a sulfonation reaction product of alpha- olefin, to obtain the titled compound easily, by recycling a neutralized substance which is partially neutralized with part of a basic solution necessary for the neutralization to a mixing zone, increasing the amount of the basic solution to the neutralization equivalent. CONSTITUTION:A sulfonation reaction product of 10-20C alpha-olefin is continuously fed from the feed pump 1 and a basic solution (e.g., aqueous solution of NaOH) from the feed pump 2 respectively to the mixing zone 3 so that the sulfonation reaction product is neutralized, the neutralized substance is partially recycled to the recycling system 7, to give neutralized alpha-olefinsulfonic acid. In the process, at the beginning 30-70wt% basic solution based on an amount necessary to neutralize the sulfonation reaction product is fed to the mixing zone it partially, the neutralized substance is recycled, and the amount of the basic solution is increased to an amount corresponding to the neutralization equivalent. By this method, the solidification of the neutralized substance resulting from salting-out action can be prevented.

摘要： PURPOSE:To carry out the recovery of mist genrated during sulfonation, by a method wherein ultra-fine particulate mist with a particle size of about 0.5-1mum is collected to a max. extent and the re-utilization of collected mist is enabled without deteriorating mist quality. CONSTITUTION:Water, at least one kind selected from alcohols shown by general formula ROH(wherein R is 1-10C alkyl) or steam is introduced into an exhaust gas in which ultrafine particulate mist with a particle size of about 0.5- 1mum is present in an amount of about 1-10g/Nm in a ratio of 1-100pts.wt. to 1pt.wt. mist. The value of about 100pts.wt. is a range of a necessary and sufficient condition coating only the surface of mist and, if a steam introducing amount does not reach the above-mentioned lower limit value, mist particle can not grow substantially. The introduction of steam into the exhaust gas is desirably carried out at a position in the vicinity of a gas-liquid separator and, if possible from the standpoint of a machine structure, it may be carried out in the gas-liquid separator.
