Abstract:
PROBLEM TO BE SOLVED: To provide an industrially favorable method for producing a salicylate by effectively suppressing precipitation of salicylic acid in devices in steps after a distillation step when producing the salicylate by transesterification. SOLUTION: The method for producing salicylate comprises distillation treatment of a reaction liquid in the presence of a proper amount of a basic compound or an epoxy compound having a higher boiling point than the generated salicylate, which liquid is obtained by transesterification of a lower alkyl salicylate with an alcohol or a phenol in the presence of a transesterification catalyst.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a pyran compound in a high yield from a hydroxypyran compound without a problem of corrosion of equipment and the like. SOLUTION: The hydroxypyran compound (I) (wherein R is a 1-12C alkyl group, an alkenyl group, an aryl group which may be substituted with an alkyl group or an alkoxy group and has 6-12 carbon atoms or the like) is subjected to dehydration reaction in the presence of an acid to produce the pyran compound (II) (wherein R is the same as defined above).

Abstract:
PROBLEM TO BE SOLVED: To provide an efficient and high productivity method for producing a pyran compound which has no restriction on a reactor. SOLUTION: An aldedhyde (II) (wherein R is a 1-12C alkyl group, an alkenyl group, an aryl group which may be substituted with an alkyl group or an alkoxy group and has 6-12 carbon atoms in total or the like) is reacted with isoprenol in the absence of a solvent to obtain a mixture of a pyran compound (I) (wherein R is the same as defined above) and a hydroxypyran compound (III) (wherein R is the same as defined above), and the pyran compound (I) is obtained from this mixture by subjecting the hydroxypyran compound (III) to dehydration reaction.

Abstract:
PROBLEM TO BE SOLVED: To obtain a triol excellent in foamability and giving a comfortable touch feeling to the hair or skin during washing and rinsing; to provide a method for easily producing the triol; and to prepare a cosmetic containing the triol. SOLUTION: This triol is represented by formula (I) (wherein R 1 is H or methyl; and R 2 and R 3 are each H or an alkyl, may combine with each other to form a 5-to 12-membered ring, and are not simultaneously H, and the total number of carbon atoms in R 2 and R 3 is 4 to 17). The triol is produced by reducing a hydroxylactone represented by formula (II) (wherein R 1 , R 2 and R 3 are the same as above). The cosmetic provided contains the triol. COPYRIGHT: (C)2004,JPO
