Gas Chromatography of Benzofuran Derivatives. II. Alkaline Hydrolysis of Benzbromarone

Hippurate Hydrolysis by Gas-Liquid Chromatography

A rapid gas-liquid chromatographic procedure was developed to determine hippurate hydrolysis by microorganisms. Bacterial cells were inoculated into 0.4 ml of 1% sodium hippurate and incubated for 2 h at 37°C. Cells were removed by centrifugation, and the benzoate released by enzyme activity was converted to methyl benzoate and analyzed by gas-liquid chromatography. This procedure is sensitive,...

hazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures

شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...

Alkaline and alkaline earth metal complexes of dianhydride derivatives of clodronate and their hydrolysis products.

Alkaline and alkaline earth metal complexes of P,P'-diacetyl- (L1(2-)); new P,P'-dipropanoyl- (L2(2-)) and P,P'-dibenzoyl(dichloromethylene)bisphosphonates (L3(2-)) and their hydrolysis products were prepared and characterized using the single-crystal X-ray diffraction technique and spectroscopy, with the intention of studying the hydrolysis and coordinating properties of these potential prodru...

Alkaline Hydrolysis of N-acetylolycine

A faster reaction of the cation is expected for the compounds with a free amino group in the acyl moiety. Such an increase was observed for Ala-Ala-pnitroan~lide b.ut not with Ala-p-nitroanilide. Fischer · et al. concluded that a larger inc-rease in k1 with the latter compound was compensated by a reductionin k2/ki. so that the observed k1k2/(k~1 + k2) term remains the same. This assumption of ...
