    摘要： A method is disclosed for preparing ammonium hydroxyalkyl sulfonate by a process of reacting ammonium bisulfite and alkylene oxide wherein the pH is maintained at a relatively low value throughout most of the time of reaction of ammonium bisulfite and alkylene oxide in order to minimize the quantity of impurities, e.g. alkylene glycol and alkanolamine, in the ammonium hydroxyalkyl sulfonate. Ammonium alkanoyl alkyl sulfonates prepared by reacting such ammonium hydroxyalkyl sulfonates with fatty acids form aqueous solutions which are clear at ambient temperatures, and thus are useful as surfactants in clear liquid products.

    摘要： N-hydroxysuccinimide monohydrate is precipitated from an aqueous solution of N-hydroxysuccinimide. N-hydroxysuccinimide monohydrate is a new compound that can be used to produce anhydrous N-hydroxysuccinimide which is substantially pure. It can also be used as a substitute for N-hydroxysuccinimide when the presence of water is not detrimental.

    摘要： Describes a method of producing N-1-alkenyl carbonylamino compounds represented by the following general formula I, ##STR1## wherein R.sub.1 is the residue of an active hydrogen functional material, n is a number from 1 to a number equal to the number of active hydrogen groups of said active hydrogen functional material, X is selected from O, S and N(R.sub.5), R.sub.5 being hydrogen, hydrocarbyl, or R.sub.5 and R.sub.1 may together form a cyclic ring, R.sub.2, R.sub.3 and R.sub.4 are each independently selected from hydrogen, C.sub.1 -C.sub.4 alkyl and C.sub.2 -C.sub.4 alkenyl. The method comprises the steps of: (a) heating 2-alkenoyl azide in the presence of a first inert solvent in a first reaction zone, the first inert solvent being substantially free of active hydrogen functional material; (b) transferring volatile product as it is formed in the first reaction zone of step (a) into a separate second reaction zone containing a reactive composition comprising active hydrogen functional material having active hydrogen groups selected from the group consisting of hydroxyl, thiol, primary amine, secondary amine and combinations thereof; and (c) withdrawing N-1-alkenyl carbonylamino compound from the second reaction zone.
