5 results about "Aromatic amine" patented technology

The invention relates to a synthesis method of an asymmetric azoxybenzene compound. According to the synthesis method, in an organic solvent, silver oxide is taken as the only promoter to carry out dehydrogenation condensation reactions. According to the synthesis method, aromatic amines and nitrosobenzene are taken as raw materials, and high efficient and selective synthesis is carried out undermild conditions to obtain the asymmetric azoxybenzene compound, which has a wide application range. The used promoter is commercial silver oxide, the synthesis raw materials are cheap and easily available; after reactions, silver oxide is converted into silver, which can be recovered and reused; the synthesis method is environment friendly, and compared with the prior art, the synthesis method ismore practical, is worthy to popularize, and is sustainable.

The invention relates to the technical field of metal degreasers, and particularly relates to an environment-friendly high-effective degreaser and a preparation method of same. The degreaser includes a component A and a component B, wherein the component A includes, by weight, 2.0-4.5 g/L of [alpha]-olefin sulfonate, 3.5-6.0 g/L of an aromatic amine oxide cationic surfactant, 1.2-4.6 g/L of lauric acid alkylolamide, 8.0-12.0 g/L of carboxymethylcellulose, 6.0-14.0 g/L of active sludge, 0.5-3.5 g/L of citric acid, 1.0-4.0 g/L of triethylene tetramine, and the balance being water; and the component B includes: 3.0-5.0 g/L of glucose, 0.8-2.4 g/L of lauryl sulfate tryptose, 1.0-3.0 g/L of agar, 2.0-5.0 g/L of inorganic salts, 100 hundred million U/L of bacillus polymyxa and the balance being water. The degreaser has strong permeability, short degreasing time, high degreasing rate and good anti-rust effects and can quickly and effectively remove oil dirt on surfaces of metal.
