Abstract: A method of homologating monosaccharides via their cyanohydrins utilizes transcyanohydrination across a phase boundary from a water-insoluble donor cyanohydrin dissolved in an organic, water-immiscible solvent to an aqueous solution of a receptor monosaccharide. This heterogeneous transcyanohydrination can be incorporated into a cyclic process where the cyanide donor is enzymatically regenerated via enzyme catalyed addition of HCN to a suitable aldehyde. The latter process can be made continous or semicontinuous by immobilization of the enzyme.

Abstract: An aldehyde (R.sup.1 CHO) and optically active 3-hydroxybutyric acid (CH.sub.3 CH(OH)CH.sub.2 COOH) are reacted to form an optically active dioxanone. This dioxanone is reacted with a compound R.sup.2 --X to form an intermediate (R.sup.1 R.sup.2 CHOCH(CH.sub.3) CH.sub.2 COOH) which is then subjected to elimination to form an optically active secondary alcohol (R.sup.1 R.sup.2 CHOH) in good yield and purity.

Abstract: Process for the production of optically-active di-[3-chloro-2-oxy-propyltrimethylammonium]-tartrate. Racemic 3-chloro-2-oxy-propyltrimethylammonium-chloride is converted by racemate resolution with optically-active tartaric acid into the optically-active di-[3-chloro-2-oxy-propyltrimethylammonium]-tartrate. Such optically-active tartrate compound is dissociated in tartaric acid to optically-active 3-chloro-2-oxy-propyltrimethylammonium-chloride and the latter is converted with inorganic cyanides. From the product, the production of optically-active carnitine nitrile chloride can be achieved.

Racemic 3-chloro-2-oxy-propyltrimethylammonium-chloride is converted by racemate resolution with CaCl.sub.2, for example, into the optically-active di-[3-chloro-2-oxy-propyltrimethylammonium]-tartrate. Such optically-active tartrate compound is dissociated into calcium tartrate and optically-active 3-chloro-2-oxy-propyltrimethylammonium-chloride, and the latter is converted with inorganic cyanides. From the product, the production of optically-active carnitine nitrile chloride can be achieved.

Abstract: A stoichiometric amount of a polyamine compound selected from the group cisting of cyanoethyl substituted tetraethylene pentamine (TEPAN), or the glycidol reaction product of cyanoethyl substituted tetraethylene pentamine (TEPANOL) is reacted with a stoichiometric amount of perchloric acid to yield an amine salt bonding agent useful in propellant compositions.This improved method prevents the generation of ammonia (as in prior art method) which has to be removed prior to use of amine salt bonding agent in a propellant composition. Also, a lesser amount of diluent water is involved in this method which offers an advantage by not having to strip an excessive amount of water by heat, purge, or vacuum means.The amine salt bonding agents prepared by this improved method are shown to be of like identity and quality as shown by IR spectroscopic examination and their testing in a propellant composition.
