Patent number: 7655820Abstract: A method for producing a molecular compound which comprises mixing and kneading a solid host compound and a solid or liquid guest compound by using a kneader and optionally followed by extruding and granulating, wherein the method further comprises one or more of the steps of holding the product at a temperature which is 50° C. or higher and not higher than the emission temperature for the guest compound, washing the formed molecular compound with a solvent capable of dissolving the guest compound, pulverizing in advance the solid host compound, and adding a poor solvent such as water prior to mixing and kneading. The method allows the production of a molecular compound having improved stability.Type: GrantFiled: September 5, 2007Date of Patent: February 2, 2010Assignee: Nippon Soda Co., Ltd.Inventors: Masato Amaike, Seiji Sasaoka, Shigeru Kawamuko, Yasuaki Hashimoto, Eiji Takemura
