摘要： A process for preparing sucrose fatty acid esters by reacting sucrose and a fatty acid alkyl ester in an aqueous reaction system in the presence of a catalyst, adding water to the reaction mixture to dissolve it, adjusting the reaction mixture to a neutral ph region, adding a neutral salt to the solution to precipitate the sucrose fatty acid esters, separating and washing the precipitate with an acidic water, and subjecting the washing liquid to ultrafiltration. The precipitate washed with the acidic water is spray-dried in the form of an aqueous slurry to give a dry powder of the sucrose esters having low HLB, and the concentrate obtained by ultrafiltration is spray-dried to form a dry powder of the sucrose esters having high HLB, and the liquid obtained by separating the precipitate is contacted with a reverse osmosis membrane to recover sucrose. According to the invention, purifed sucrose fatty acid esters can be obtained without using an organic solvent, while sucrose can be recovered in high yield.

摘要： The invention provides a temperature switch material capable of detecting a very low temperature not higher than 150 K. It also provides a light switch material for detecting light in the ultraviolet region. It further provides a switch material suited for use as a substrate for thin oxide layer formation thereon. The switching material utilizes an abrupt change in photoelectric current as produced upon phase transition of SrTiO.sub.3 at a low temperature. The photoelectric switch or temperature switch utilizes the change in photoconduction spectrum upon irradiation of SrTiO.sub.3 with light in the 3 eV-5 eV ultraviolet region. A switch is available by varying the intensity of irradiating light thereby controlling the transition temperature.

摘要： A process for the (co)polymerization of a monomer material, which includes at least an acrylonitrile monomer as an essential component, at a temperature of 80.degree. C. or higher by bulk or solution polymerization while allowing said monomer material to evaporate. The (co)polymerization is conducted while providing a vapor phase over a polymerization mixture in a reaction tank. During the (co)polymerization, the temperature of the vapor phase is maintained in a range of from 30.degree. C. to 65.degree. C. so that the polymerization is conducted without substantially releasing vapor, which is evaporated from the polymerization mixture, to outside of the reaction tank. By cooling the vapor phase of the reaction tank and maintaining its temperature in the above specific range in accordance with the present invention, it is possible to avoid mixing of a gelled polymer in a product and also to effectively remove reaction heat at the time of the (co)polymerization.
