NOVELTY - Producing organic compounds e.g. dichloropropanol involves producing glycerol from renewable raw materials; and subjecting the produced glycerol to a reaction with a chlorinating agent in presence of acetic acid or its derivatives. The glycerol is obtained by conversion of animal fats, or obtained during the manufacture of biodiesel. The crude glycerol is optionally purified by e.g. distillation, before the reaction with chlorinating agent.    USE - For producing organic compounds such as dichloropropanol and epichlorohydrin (claimed).    ADVANTAGE - Glycerol obtained from renewable raw materials is used as the starting product for producing organic compounds, rather than the synthetic glycerol obtained from petrochemical resources. Hence, the process produces large number of organic compounds, while minimizing the consumption of natural oil resources. The process produces dichloropropanol by reacting glycerol with the chlorinating agent, with the exception of a batch reaction carried out in presence of acetic acid or its derivatives. The pseudo-azeotropic composition comprising dichloropropanol, hydrogen chloride and water, that is difficult to separate by distillation in prior art, is now separable at temperatures less than 40 (preferably at most25)degreesC into dense organic phase and lighter aqueous phase. The process reduces the volume of aqueous effluents of epichlorohydrin production, and minimizes the content of these effluents in organochlorinated by-products e.g. chlorinated ethers. During synthesis of epichlorohydrin, the 1,3-dichloropropan-2-ol is unreactive with the epichlorohydrin, preventing the formation of organo-chlorinated by-products. In addition, the quality of production effluents is improved by reducing the formation of chlorinated impurities. The yield of epichlorohydrin is also improved.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a process for separation of a mixture containing at least water, dichloropropane and hydrogen chloride; and    (2) a pseudo-azeotropic composition comprising dichloropropanol, hydrogen chloride and water.
