摘要:
A method of decomposing halogenated aromatic compounds safely without fail, which comprises bringing a solution of a halogenated aromatic compound in a hot-alkali-resistant polar solvent into contact with an alkaline substance at about 100 to about 300 DEG C to decompose the aromatic compound and removing the salt and alkaline substance precipitated in the solvent to recycle the used solvent.
摘要:
A feed for fishes and shellfishes prepared from lees of squeezed plants as a plant waste and having a high efficiency of feeding. The feed comprises a matrix material containing the product of microbial fermentation of the lees or the product of pulverization thereof and a mixture of lower amino acids (A) bearing two to three carbon atoms and higher amino acids (B) bearing at least four carbon atoms in a molar ratio, A/B, of 1 to 40.
摘要:
A method of removing halogenated aromatic compounds contained in small amounts in a hydrocarbon oil comprising mainly nonaromatic hydrocarbon oils safety without fail. The method comprises bringing the hydrocarbon oil into contact with a heat-resistant alkaline polar solvent in the presence of an alkaline substance at about 100 DEG C to about 300 DEG C and separating the nonaromatic hydrocarbon oils and the solvent from each other.
摘要:
A method of decomposing a halogenated aromatic compound with an alkaline substance safely without fail, which comprises bringing the aromatic compound into contact with the alkaline substance in an aprotic polar solvent at a temperature ranging from about 150 to about 300 DEG C for about one to about ten hours, the alkaline substance being present in an amount of about 5,000 mg per kilogram of the reaction mixture as a whole in starting the reaction.
