| Title compd. (I) was prepd. by reacting lysine salt derived from lysine derivs. with p-isobutylphenylpropionic acid. I was water sol. and had higher antirheumatic and analgetic activity than 2-(p-isobutylphenyl)propionic acid. Thus, I was more effective than the acid in suppressing inflammation in rats due to injection of kaolin. The acute i.p. LD50 of I was 149.7 mg/kg in mice and 485.3 in rats. | ||||||

| The present invention provides an acid water and residue separation device for a mother liquor discharged from an oxidation unit of pure terephthalic acid (PTA), comprising a precipitation tank; a precision filtration tank; and an auxiliary crystallization device, wherein the mother liquid is A mother liquid tank flows out into the precipitation tank and crystallizes and precipitates solid particles therein, and then flows out into the precipitation tank to enter the precision filter tank for filtration, and a part of the filtered clarified mother liquid flows back to the mother liquid tank, and another part flows into the auxiliary tank. The crystallization apparatus adjusts the conditions of the clarified mother liquid, returns to the precipitation tank, and circulates the above-mentioned filtration to obtain a clarified mother liquid. The solid residue adhering to the precision filtration tank is discharged from the bottom of the precision filtration tank through a cake program after the filtration is stopped, and collected and then subjected to cobalt manganese recovery treatment. The creation can improve the high energy consumption and high power consumption of the vaporized acid water in the traditional process, and can also reduce the loss of cobalt and manganese bromine catalyst caused by the mother liquor discharge, thereby achieving the purpose of energy saving and consumption reduction. | ||||||
