摘要： Polyurethane elastomers are made by reacting organic polyisocyanates with compounds having at least two groups containing isocyanate-reactive hydrogen atoms and a molecular weight of from 400 to 10,000 and a 1,4-monoanhydro-tetritol in accordance with techniques known to those in the art. Known chain-lengthening agents, auxiliaries and additives may be included in the reaction mixture. The reaction mixtures employed in the process of the present invention have a longer pot life than prior art reaction mixtures. The elastomers produced by this process are shrink stable.

摘要： A process for the preparation of 1,4-3,6-dianhydro-hexitols from hexitols by elimination of water is described, characterized in that gaseous hydrogen halide is used as the acid dehydrating agent optionally with carboxylic acids, carboxylic acid halides and/or carboxylic acid anhydrides in quantities of up to 600 mol percent, based on the hexitols, as cocatalysts. The reaction is carried out in the absence of water and organic solvents, preferably using gaseous hydrogen chloride, temperatures of up to 300.degree. C. and pressures of up to 250 bar. Very high yields are obtained after working up of the product by distillation or extraction.

摘要： Liquid dianhydrohexitol mixtures are prepared from diacylation products of hexitols and compounds such as organic carboxylic acids, carboxylic acid anhydrides, carboxylic acid halides, ketene and carbonic acid ester derivatives. More specifically, such diacylation products are simultaneously dehydrated and isomerized by subjecting them to a temperature of at least 130.degree. C. in the presence of a strong acid to yield diacylated dianhydro-hexitol isomer mixtures. These isomer mixtures are then converted to dianhydro-hexitol isomer mixtures by hydrolysis or transesterification. Suitable strong acids include proton acids, Lewis acids and heterogeneous acid catalysts (e.g., ion exchange resins). The mixtures of the present invention are characterized by a minimal tendency towards crystallization. These mixtures are particularly useful as chain extending agents in the production of polyurethanes.
