    摘要: There are provided compounds which are alkyl sulfonates substituted on a 5-membered heterocyclic or cyclic ring. The hetero-substituents of the ring may be O, S, R 2 N, R 3 R + 4 N ,
    where R 2 , R 3 and R 4 are the same or different substituted or unsubstituted, and are hydrogen, alkyl or aryl. Optionally, the hetero-substituent may be replaced by R 3 R 4 C . The alkyl sulfonate substituent is in the 3 position of the ring and a substituted or unsubstituted alkyl substituent is in the 4 position of the ring. The compounds may be prepared by reacting X(CH 2 CH-CHR) 2 , where X is the above mentioned hetero-substituents or R 3 R 4 C, with a bisulfite salt.

    摘要: p-Menth-6-ene-7-methylol-2-sulphonic acid, p-menthane-7-methylol-2-sulphonic acid, p-menthane-7-sulphonic acid and p-menthane-2-sulphonic acid and their alkali metal, alkaline earth metal, ammonium and alkylolammonium salts are disclosed. A process is provided for preparing the ammonium salts thereof. A method is presented for increasing the solubility of an only partially water-soluble material using these sulfonic salts as a hydrotrope.

    摘要: Optical resolution of (±)-phenyl glycin and/or (±)-camphor sulfonic acid by way of diastereomeric salts thereof can be carried out efficiently by using mixtures of optically active forms and racemic forms of phenyl glycin and camphor sulfonic acid as mutual resolution agents in a liquid medium so as to form and crystalize the two kinds of the diastereomeric salts alternately.
