Title: Preparing organopolysiloxanes by emulsion
Inventor: ARIGA KINJI
IPC: C08G77/50
Filed: 1968-10-10
Abstract: Organosiloxanes, organoalkoxysilanes and/or silarylenes are emulsion polymerised in presence of alpha, omega-bissulpho-phenyl- or -naphthyl- alkanes. Organopolysiloxanes are obtained in good yield and as very stable emulsion using these new catalysts. Emulsions can be used as plasticiser for various fibres and, when treated with peroxide or organo-Sn catalyst, for production of tough films with high thermal and weathering stability. Starting materials have gen formulae RnSiO4-n/2, RnSi(OR)4-n and HO(R2)SiASi(R2)OH (in which R is H, monovalent (halo)hydrocarbyl or alkyl carboxylate group; n is 1, 2 or 3; A is arylene, e.g. (bis)phenylene etc.). Catalysts are derivatives of C4-12 alkanes.

Title: Insulin purifcn - by partition chromatography on crosslinked dextran gel
Inventor: LANGNER DIETRICH
IPC: C07K14/62
Filed: 1972-03-16
Abstract: Process for purification of insulin and insulin derivatives by subjecting to partition chromatography on an epichlorohydrin-crosslinked dextran gel, the OH groups of which are for the most part alkylated, in an aqueous-organic solvent system contg. (a) 4-5C alcohols and (b) 1-3C carboxylic acids and/or ammonia or an organic base having a pKa value of ca 5.1-11. The procedure enables both natural and synthetic insulin to be freed from ballast substances, even when these are present in considerable excess in crude synthetic insulin. Even small differences in physical properties are sufficient for the separation to be successful; thus, insulin can be smoothly separated from des-phenylalanine-B1-insulin. The separation is particularly smooth when applied to insulin derivatives with different degrees of acylation, e.g. mono-, di- and tri-acyl-insulins. The new procedure avoids the need for adding urea, and high rates of throughput can be achieved (40 cm. x 2 m. column permits 400-500 g. of insulin to be purified in 24 hrs.).
