Long chain alkanesulfonates and 1‐hydroxy‐2‐alkanesulfonates: Structure and property relations

AbstractEven chain sodium alkanesulfonates from the Strecker reaction, odd chain sodium alkanesulfonates from the alkaline decarboxylation of ॅ‐sulfo acids, and sodium 1‐hydroxy‐2‐alkanesulfonates from the reduction of esters of ॅ‐sulfo acids were compared with respect to Krafft point, critical micelle concentration, detergency and foam height. Sodium alkanesulfonates and crude fusion products from the ॅ‐sulfo acids (mixtures of alkanesulfonates of one less carbon atom with a lesser amount of a soap of two less carbon atoms) are more soluble and have better detergent and foaming properties. Sodium 1‐hydroxy‐2‐alkanesulfonates resemble monosodium salts of ॅ‐sulfo acids.Alkanesulfonic acids and 1‐hydroxy‐2‐alkane‐sulfonic acids obtained from the sodium salts by ion exchange have lower Krafft points and are more readily soluble. The critical micelle concentrations of 1‐hydroxy‐2‐alkanesulfonic acids and ॅ‐sulfo acids are nearly the same and about equal to those of alkanesulfonic acids of one less carbon atom.

Preparation of Metal Salts of Alkanesulfonic Acids

A series of lanthanum salts of the lower alkanesulfonic acids were prepared for the purpose of evaluating their antiperspirant, astringent, and/or deodorant activity.

Copolymerization of butadiene and styrene in the oxygen–1‐alkanesulfinic acid system

AbstractThe copolymerization of butadiene and styrene in an alkanesulfonic acid emulsion with air as the oxidizing agent and higher alkanesulfinic acids as oil‐soluble reducing agents has been studied. Dodecyl mercaptan and ferric salts are needed to make this recipe function well. The optimum pH for rapid polymerization was found to vary with the different alkanesulfinic acids (C8 to C18 in the even‐numbered straight‐chain series). Tetradecanesulfinic acid is the most active reducing activator in this series. The conversions with butadiene and styrene are about 75–80% at 30° in six hours and these copolymers have normal solubility and inherent viscosities.
