    摘要： PROBLEM TO BE SOLVED: To obtain a material which solves the drawbacks of a polyimide resin while possessing advantages of conventional polyimide resins. SOLUTION: A polyimide precursor is composed by using an amino group- containing phenol derivative represented by formula (1) (wherein R 1 , R 2 and R 3 are each a 1-9C alkyl group, a 2-10C alkoxy group, COOR (wherein R is O, a 1-6C alkyl group) or hydrogen; R 4 and R 5 are each a 1-9C alkyl group or hydrogen; X is S, SO 2 , C(CH 3 ) 2 , CH 2 , C(CH 3 )(C 2 H 5 ) or C(CF 3 ) 2 ; and (n) is an integer of at least 1).

    摘要： PROBLEM TO BE SOLVED: To decrease engine deposits, particularly intake valve deposits, by using the subject compd. as a fuel additive to a fuel compsn. SOLUTION: This substd. biphenyl polyalkyl ester is expressed by the formula. In the formula, R1 is H or hydroxyl; R2 is hydroxyl, cyano, nitro, amino, aminomethyl, an N-alkylamino or an N-alkylaminomethyl each having a 1 to about 6c alkyl, or an N,N-dialkylamino or an N,N-dialkylaminomethyl each having independently 1 to about 6C alkyl groups; R1 and R2 are located at the ortho positions each other and are located at the meta or para positions to an adjacent phenyl substituent group; and R3 is a polyalkyl group having an average mol.wt. ranging from about 450 to about 5,000. The substd. biphenyl polyalkyl ester in a hydrocarbon fuel has a concn. ranging from about 50 to about 2,500 ppm by wt.

    摘要： PROBLEM TO BE SOLVED: To produce a keto-acid that is useful as an intermediate for production of fluoran compounds used as pressure- or heat-sensitive recording dyestuffs by reading a specific m-aminophenol with phthalic anhydride in an organic solvent at a low cost in an economical aspect as well as in the aspect of environmental preservation by the use of a small quantity of the solvent. SOLUTION: This keto-acid of formula II (e.g. 4-N,N-dibutylamino-2- hydroxy-2'-carboxybenzophenone) is produced by reacting an m-aminophenol of formula I [R1 and R2 are each a 1-18C alkyl, 4-8C (substituted) cycloalkyl, etc.] (e.g. N,N-di-n-butylaminophenol) with phthalic anhydride in a quantity of 0.5-20mol to 1mol of the m-aminophenol in an organic solvent (e.g. toluene) in a quantity of less than 0.5 pt.wt. to 1 pt.wt. of the m-aminophenol at 60-120 deg.C for 3-40hr., and cooling the resultant mixture to 0-60 deg.C.
