摘要： PURPOSE:To efficiently obtain 4-(3-oxoalkyl)phenol useful as intermediate of an agrochemical, a perfume, etc., in a high yield by reacting phenol with beta- hydroxyketone in the presence of a specific catalyst. CONSTITUTION:The compound of formula II (R1 is R2) is obtained by reacting (A) phenol with (B) a beta-hydroxyketone of formula I [R2 is 1-7C (branched) alkyl] in the presence of (C) a heteropolyacid catalyst in liquid phase. Further, in the production of the objective compound, an alkyl vinyl ketone of formula III (R3 is R2) may be used in stead of the compound of formula I as the reaction component B. The catalyst component C is preferably a heteropolyacid which has the configuration of the condensate of an oxide selected from among molybdenum oxide, tungsten oxide and vanadium oxide with the oxiacid of an element selected from among P, Si and Ge at atomic ratio of the former to the latter of 1-12.

摘要： PURPOSE:To produce a beta-hydroxyketone compound in high yield while suppressing side reactions essentially without generating waste water by batch process or continuous process having excellent operability. CONSTITUTION:A beta-hydroxyketone compound is produced by the condensation reaction of formaldehyde and a ketone. In the above process, the supply of the formaldehyde is carried out in the form of a mixed liquid produced by condensing a thermal decomposition gas of paraformaldehyde diluted with vapor of ketone, a mixed liquid produced by dissolving paraformaldehyde in a ketone or a dispersion liquid produced by dispersing paraformaldehyde in ketone in the form of fine particles.

Then, the objective compound expressed by formula III or formula IV is isolated by azeotropy with water after finishing the reaction. Besides, preferably, after isolation of the objective compound, hydrogen chloride in the reaction mixture is distilled away and chlorine is blown into the system to recover ferric chloride. Concentration of ferric chloride in the aqueous solution before the reaction is 10-60% and using amount of the ferric chloride is 2.0-4.0mol for 1mol of the compound expressed by formula I and 4.0-8.0mol for 1mol of the compound expressed by formula II.
