摘要： N-alkyl amino phenols, such as N-ethyl-m-amino phenol are produced in high yield and with high purity by reacting a divalent phenol, such as resorcinol, with an alkylamine, such as ethylamine, in the absence of catalyst and solvent, at a temperature of 120.degree.-210.degree. C. under elevated pressure in an inert gas atmosphere. In a first embodiment, the resulting reaction mixture is acidified to convert the N-alkylaminophenol to its water soluble salt and the resulting aqueous layer is separated from the oily layer. The aqueous layer is rendered alkaline to liberate N-alkylaminophenol as an oily layer. The N-alkyl-aminophenol oily layer is then separated from the aqueous layer and distilled. In an alternative embodiment, the reaction mixture resulting from the reaction between the divalent phenol and alkylamine is combined with an aqueous solution of an alkali to convert unreacted phenol to its water soluble salt while the product N-alkylaminophenol remains in an oily phase which is separated from the aqueous phase. An organic solvent is used as an extractant. The recovered N-alkylaminophenol organic solution is then distilled to recover N-alkylaminophenol. Purities of the recovered N-alkylaminophenol in excess of 95% can be achieved.

摘要： A process for preparing 2-unsubstituted imidazoles which comprises reacting an .alpha.-hydroxycarbonyl compound with a formamide in such amounts as to make the molar ratio of said formamide to said hydroxycarbonyl compound not more than 2 at a reaction temperature of 100.degree.-170.degree. C. in an atmosphere of ammonia gas. According to this process, 2-unsubstituted imidazoles may be obtained in very high yields. In addition, because no great excess of formamide is used in carrying out the reaction, an effect of not requiring the recovery operation incident to decomposition of formamide is obtained as well. And by removing formic acid formed as a by-product by the reaction, a reactor and separation equipment such as a distillation column are not corroded, and imidazoles of a high purity can be obtained.

摘要： The present invention provides resin compositions containing thermoplastic resins. Thermoplastic resins employable for the compositions are polyolefin resins, polyester resins, polystyrene resins, polyamide resins and polyphenylene ether resins. The present invention can be particularly effected by using polyamide, particularly, specific aromatic polyamides.In the present invention, the resin compositions can be improved in various chemical and physical properties such as flame-retardance, moldability, color tone, heat stability, mechanical strength by the use of other resin component and stabilizers such as halogenated organic compounds, modified polyolefins, antimony compounds, phosphorus-containing compounds, amine- or phosphorus-type stabilizers.
