摘要:A process for the production of a phthalocyanine pigment having a clear color tone, a high tinting strength and a finely milled structure by an efficient and economical process, in which the pigmentation from a phthalocyanine crude can be carried out without removing an aromatic hydrocarbon solvent used in the synthesis of the phthalocyanine crude, the process comprising thes steps of n (a) reacting phthalic anhydride or its derivative, urea or its derivative and a catalyst in an organic solvent to synthesize a phthalocyanine crude, n (b) wet-milling a slurry of the synthesized phthalocyanine crude in the presence of a milling medium without removing the aromatic hydrocarbon solvent, and n (c) removing the organic solvent from the slurry of the milled product, purifying the milled product and drying the milled product with a spray type dryer.

标题 :Facile synthesis of phosphonomethylglycine from phosphonomethyliminodiacetic acid
发明人：CULLEN BARRY A; PARKER BRIAN A
权利人:HAMPSHIRE CHEMICAL CORP
摘要:A process for the preparation of phosphonomethylglycine in nearly quantitative yields which eliminates the use of a noble metal co-catalyst and its concomitant problems. The oxygen-containing gas is replaced with the much more chemically active hydrogen peroxide, which in combination with activated carbon, oxidizes the PMIDA to PMG in very high yield. The amount of oxidant allowed to react with PMIDA is a function of the concentration of oxygen in the gaseous reaction products, and is controlled by monitoring that concentration. In another embodiment, the oxidizing agent is an oxygen-containing gas. In either case, the concentration of oxygen in the gaseous reaction product is monitored to determine the end point of the reaction.

标 题 :Method for the preparation of maleimides

摘要:In accordance with the present invention, there are provided improved methods for the preparation of maleimide monomers. This new method for the synthesis of maleimides is clearly superior to those documented in the prior art. Furthermore, the invention method utilizes materials with reduced toxicity, thus the overall process has a minimal impact on the environment. Thus, in accordance with the present invention, it has been discovered that certain amine salts can be successfully used to replace the polar, aprotic solvents cited in the prior art for the cyclodehydration of maleamic acids. The use of these salts provides competitive reaction times and product yields relative to results obtained with the polar, aprotic solvents. These salts have the advantage of having no vapor pressure and, therefore, have no possibility to co-distill with the water produced by the cyclodehydration reaction. Furthermore, such salts can be tailored to have desirable solubility characteristics (i.e., soluble in the refluxing azeotropic solvent, but insoluble at room temperature) that permit their easy removal from the reaction product. Such salts are not destroyed during the cyclodehydration reaction and, therefore, can be efficiently recycled again and again.
