    摘要: A two-step method for introducing acrylic functions into high molecular weight natural resins, under mild conditions, without the risk of gellation, wherein an acrylated natural resin ester is prepared by esterifying one or more of the sterically hindered hydroxy groups of the natural resin ester in an inert solvent with a 3-halopropionic acid, to form a 3-haloproprionate ester of the natural resin ester and dehydrohalogenated the 3-halopropionate ester by reacting it with an organic base.

    摘要: A process is described for preparing carboxylic acid esters of hexitols by rapidly heating the hexitol and carboxylic acid to 210.degree. to 250.degree. C. in the presence of alkaline catalysts, continuing the esterification reaction at this temperature, while simultaneously driving off the water formed, until an acid number of 2 to 15 has been reached, and then rapidly cooling down to at least 145.degree. C. This process produces hexitol carboxylates which are essentially free of anhydro compounds and have good color quality. The hexitol carboxylates are surface-active substances, in particular high-grade emulsifiers and lubricants.
