    Abstract: PURPOSE:Raw vegetables containing a large amount of fibrous matter are frozen, crushed, heat-treated for a short time to decomposes enzymes, then immediately cooled to prepare said stuff for vegetable dish that contains useful nutrients without deterioration, decomposition and effluence and can be used without passing through a strainer. CONSTITUTION:Raw vegetables containing a large amount of fibrous matter or beans are frozen with liquid nitrogen to lower than -5--6 deg.C, preferably -20- -50 deg.C and crushed into a fine powder of 20-200 mesh. The powder is heated at 70-100 deg.C for 1-2min to decompose enzymes and immediately cooled, then, when necessary, canned, bottled or frozen.

    Abstract: PURPOSE:To extract the essence effectively in a short time, without decomposing and deteriorating tasting components, by freezing and finely pulverizing an animal soup stock of cattle or aquatic animals with liquid nitrogen, and by extracting soluble constituents with hot water. CONSTITUTION:An animal soup stock is frozen with liquid nitrogen and finely pulverized. The fine powder is then extracted with hot water to give soluble constituents. Ordinary materials for soup, e.g. domestic fowl, cattle, and aquatic animals, may be used as the materials; however, bones, cartilage, horny substances, sinews or entrails which contain components easily deteriorated by heating for a long time may be suitably employed. Liquid nitrogen spray may be used as the freezing and pulverizing means. This method permits effective extraction of tasting components in a short time of several to 20min and inhibition of deterioration and decomposition of proteins and amino acids.

    Abstract: PURPOSE:To obtain the titled compound industrially useful as a raw material of the organic synthesis, etc. directly in high yield, by catalytically reacting methyl acetate with carbon monoxide under the vapor phase conditions in the presence of a rhodium catalyst supported on a porous inorganic carrier. CONSTITUTION:Methyl acetate is catalytically reacted with carbon monoxide in the presence of a rhodium catalyst supported on a porous inorganic carrier substance, preferably in the presence of a reaction accelerator, e.g. methyl iodide, at 150-300 deg.C, preferably 200-250 deg.C, under the vapor phase conditions to give the titled compound. Preferably, the reaction pressure is ordinary pressure -30kg/cm , and the raw material gas flow rate (GHSV) is about 500-10,000. The catalyst is prepared by supporting any rhodium compound, e.g. rhodium oxide, on the porous inorganic carrier substance, e.g. active carbon or alumina, by the conventional method and used as a fixed bed or fluidized bed.

    Abstract: PURPOSE:To isomerize 3,3-dichloropropene, a by-product in the preparation of allyl chloride, into 1,3-dichloropropene and to use advantageously as a nematocide, in the presence of a metal salt of zinc, iron, copper, tin, titanium, or vanadium as a catalyst. CONSTITUTION:3,3-Dichloropropene, which is a by-product in the preparation of allyl chloride by chlorination of propylene and has been mostly discarded and burned, is efficiently isomerized into 1,3-dichloropropene efectively in the presence of a metal salt (e.g. a halogenide, napthenate, etc.) of zinc, iron, copper, tin, titanium or vanadium. 3,3-Dichloropropene is formed as a by-product in the form of a mixture with compounds having nearly the same boiling point, but can be directly isomerized without separation.
