专利号:US-5523434-A 优先权日:1995-03-15 标 题 :Synthesis of bleach activators 发明人:BURNS MICHAEL E; SIMPSON ANTHONY J 权利人:PROCTER & GAMBLE 摘要:The synthesis of phenol sulfonate esters of alkanoyl amino acids is conducted in the presence of aqueous base to provide bleach activator compounds. Thus, the acid chloride of N-nonanoyl-6-aminocaproic acid is reacted with the sodium salt of p-phenol sulfonate in the presence of water at a pH in the range of about 9 to about 12 to yield the corresponding phenol sulfonate ester. The synthesis of the phenol sulfonate ester of the monononyl amide of adipic acid is also illustrated.

The genetic engineering bacterium for de novo synthesis of cis,cis-muconic acid (MA) by taking glucose as the substrate disclosed in the present invention is modified with chassis microbes, and includes recombinant Corynebacterium glutamicum for a cis,cis-muconic acid pathway construction module and an intermediate high-yield module. Production capacity of strains is greatly improved; MA of 90.2 g/L is finally obtained in fermentation liquor; and possibilities are provided for green and low-cost production of numerous chemicals such as adipic acid and nylon-66.

This process is particularly useful since it is centered around the use of stirred autoclaves for the synthesis of the 6T oligomer and the semi-crystalline or amorphous polyamides which are subsequently combined in a twin screw extruder equipped for devolatilization of water of reaction. It can also be used for the modification of existing semi-crystalline or amorphous polyamides (not necessarily phthalamides) with low levels of 6T.
