摘要:3-Halosulfonylthiophene-carboxylic acid compounds are manufactured by reacting 3-ketothiophane-carboxylic acid compounds with sulfonic acid compounds, reacting the end product from the 1st reaction stage with alkali metal polysulfides, reacting the end product from the 2nd stage with a dehydrogenating agent and finally reacting the end product from the 3rd stage with halogen and water. The products are starting compounds for the manufacture of drugs, dyes and crop protection agents and have an anti-inflammatory, analgesic and anti-rheumatic action. In particular, the end products I are starting materials for the manufacture of sweeteners which are non-toxic and free from an after-taste, flavor-improving agents, diabetic aids and feedstuffs, and provide the means of a simple and economical synthesis of thiophene-saccharins.

摘要:The present disclosure provides methods for modifying polymeric resin materials after polymerization to make fine adjustments in the chemical or physical properties of the resin, or in modifying the structure of the polymer chains. The resulting resins may be useful in forming toner particles. In embodiments, a polymeric resin may have epoxy groups added to its backbone to increase its melting point. The resulting polymer, sometimes referred to herein as an epoxidized polymer, may, in turn, be reacted with wax-like components, to increase the compatibility of the polyester with waxes utilized in forming toner particles. In other embodiments, the resulting epoxidized polymer may be reacted with components possessing carboxylic acid groups to adjust the acid value and weight average molecular weight of the resin.
