An object of the invention is achieved by a method for producing a composite material, including the steps of combining a resin precursor and a reinforcing fiber and carrying out a polymerization reaction of the resin precursor. That is, a thermoplastic resin composite material having high strength can be obtained by the production method.

Method for producing composite material and composite material

The present invention provides a cutting method comprising a cutting step of cutting a workpiece material with a cutting tool to thereby form a through-groove in the workpiece material, wherein in the cutting step, the through-groove is formed in the workpiece material by cutting the workpiece material with the cutting tool while contacting a cut-assisting lubricant with the contact portion of the cutting tool with the workpiece material and/or the contact portion of the workpiece material with the cutting tool, and the workpiece material comprises a fiber reinforced composite material.

Cutting method for fiber reinforced composite material

Disclosed is a process for the preparation of a catalyst for the synthesis of methyl formate by dehydrogenating methanol in the gaseous phase, said process being characterized in that (A) at least one phosphate selected from the group consisting of copper phosphates, zinc phosphates and aluminum phosphates, and (B) at least one chloride selected from the group consisting of copper chlorides, zinc chloride, aluminum chloride, alkali metal chlorides and alkaline earth metal chlorides and/or (C) at least one compound selected from the group consisting of alkali metal compounds (exclusive of halides) and alkaline earth metal compounds (exclusive of halides) are added to copper oxide, zinc oxide and aluminum oxide. The catalyst obtained according to this process has a high activity for preparing methyl formate by dehydrogenating methanol in the gaseous phase, and this catalyst is excellent in the heat resistance and durability and has a high mechanical strength.

Process for preparation of catalysts

Dimethyl formamide is produced in high yield with good selectivity by reaction of monomethylamine and trimethylamine, or together with dimethylamine, with carbon monoxide in the presence of metallic iron or an iron compound such as oxide, hydroxide, sulfide, inorganic acid salt, organic acid salt or carbonyl compound of iron.

Process for producing dimethyl formamide

Dimethyl formamide with a high purity is produced in a high yield and a high selectivity by reaction of a mixture of monomethylamine and/or monomethyl formamide and trimethylamine, or the mixture further containing dimethylamine with carbon monoxide in the presence of metallic iron or an iron compound as a catalyst and hydrogen gas at a volumic rate of H.sub.2 /CO of 0.05-3.

A process for preparing a methylphenol from an alkylbenzene which process comprises oxidizing by molecular oxygen an alkylbenzene having one secondary alkyl group and 1-3 methyl groups of the general formula I ##STR1## where R is a secondary alkyl group and n is an integer of 1-3, acid-decomposing the oxidation product solution in the presence of an acid catalyst, stopping the acid-decomposition reaction before its completion, hydrogenating the acid decomposition product solution in the presence of a hydrogenation catalyst in the presence or absence of a solvent, and recovering the resulting methylphenol of the general formula II ##STR2## where n is an integer of 1-3 from the hydrogenation product solution.
