Abstract: PROBLEM TO BE SOLVED: To suitably foam so that refractory performance is achieved to a maximum limit and to suppress a thermal influence to an FRP material to a minimum limit by providing a low temperature foamable refractory substance on at least one surface of the material, and covering the substance with a metal thin film. SOLUTION: A refractory substance 1 made of an FRP has a structure in which an FRP material 2 made of an FRP veneer, a layer of a low temperature foamable refractory substance 3 fixed to one side surface of the material 2 and a metal thin film 4 are provided so that the substance 3 is covered with the film 4. The film 4 is formed in a structure in which in the case of foaming to bulge the substance 3, the substance 3 is formed developabley in its bulging direction. Thus, this can be easily developed in a shape without operating an unnatural tensile stress or the like at the film itself. An edge of the film is fixed to the material to thereby enclose the substance with the developed film during or after foaming.

Abstract: PURPOSE:To obtain a (Z)-7-decene-4-olide or a new (E)-7-decene-4-olide in high yield and high purity while suppressing production of by-products which hinder the purification by reacting an oxolactic acid ester with a Grignard reagent in the presence of a transition metal salt. CONSTITUTION:An 4-oxolactic acid ester of formula I (R is a 1-4C alkyl) is reacted with a Grignard reagent in the presence of a transition metal salt (especially preferably a metal salt selected from Mn, copper and iron) to provide the objective (Z)-7-decene-4-olide of formula II or the objective new (E)-7- decene-4-olide of formula III. When a (Z)-3-hexenylmagnesium halide is used as the Grignard reagent, the Z substance of formula II is obtained. When an (E)-3-hexenylmagnesium halide is used as the reagent, the E-substance of formula III is obtained. The compounds of formula II and formula III are useful as perfume compounds or raw materials for compounding perfumes.
