Alkynol compounds represented by the formula (1) (wherein R1 to R6 and R6 to R10 each represents a hydrogen atom or a lower alkyl group, and R11 represents a lower alkyl group or a group represented by the formula (II) (wherein R1 to Rs and R6 to Rio are as defined above, provided that at least one of R1 to R5 and R6 to R10 is a lower alkyl group) form complex crystals with alcohol when added to an aqueous alcohol solution, and can be used in separating alcohol from an aqueous alcohol solution.
An antimicrobial composition is provided in which the skin irritation of isothiazolone type compound is decreased and the injection operation properties thereof is improved by forming it as an uniform solution. The composition contains isothiazolone type compound and a compound which decreases the skin irritation of the former in a molar ratio of 1:0.1-50 and is dissolved in a solvent.
A drainage slime remover capable of spreading a solution of a solid over slime generated wall surface portions, comprising a solid containing a microorganism growth retarding substance and a container which has a shape for permitting the installation thereof at the inlet or upper portion of a drain outlet and stores the solid characterized in that the container has drain flow-in holes having an opening capable of controlling a drain flow-in amount and provided in the upper surface or the upper side portion of the container and solution flow-out holes having an opening capable of controlling a flow-out amount of a solid solution and provided in the bottom or the lower side portion of the container or additionally in the side surface thereof, and a slime preventing/removing agent which can remove slime from portions such as kitchen sinks and bathroom drain outlets where slime is grown by metabolites such as miscellaneous germs and mildews and which can prevent the occurrence of slime safely and for an extended period of time.
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.
一种生产分子化合物的方法,包括使用捏合机将固体主化合物和固体或液体客体化合物混合并捏合,可选择随后进行挤压和造粒,其中该方法进一步包括以下一个或多个步骤:将产品保持在 50 ° C 或更高的温度下,且不高于客体化合物的发射温度;用能够溶解客体化合物的溶剂清洗已形成的分子化合物;提前粉碎固体主化合物;以及在混合和捏合之前加入贫溶剂,如水。这种方法可以生产出稳定性更好的分子化合物。
