in recent years there has been considerable interest in the synthesis and separation of enantiomers of organic compounds especially because of their importance in the biochemistry and pharmaceutical industry. high-performance liquid chromatography is a very useful method for the direct separation of enantiomers. however, about 30−40 years ago, commercially available chiral stationary phases wer...

Rice tablets which are also with trade names of “Celphos” and / or “Quick phos”, will release dangerous gas of phosphine (PH3), after ingestion and contact with gasterointestinal and even environmental humidity. The resulting ghosphine as a non-visible gas with garlic or decaying fish odor; which its allowed non-toxic ratio in environment is 0.3 PPM, and a 3 gum tab...

Palladium doped silica membranes were synthesized by the sol-gel method using two different procedures. The first palladium-doped silica membrane (M1) was synthesized with a coating of four layers of silica-palladium sol. The second membrane (M2) was synthesized with a coating of two silica layers followed by a coating of two silica-palladium layers. Scanning electron microscopy (SEM) proved th...

Analogue electronic networks can be synthesised by genetic optimisation. Active linear networks containing a single operational amplifier have been generated to meet both frequency-domain and time-domain specifications. In spite of the fact that no expert rules are built into the synthesis program, the networks generated are practical and effective. Introduction Numerical optimisation is rightl...

بازیافت گوگرد از گاز اسیدی در پالایشگاه گاز شهید هاشمی نژاد بر مبنای روش کلاوس صورت می پذیرد. حدود 54 درصد از گاز اسیدی درون کوره واکنش به گوگرد تبدیل می شود و مابقی در سه مرحله مبدل کاتالیستی واکنش می دهد. جهت جداسازی گوگرد تولید شده در هر مرحله پس از انجام واکنش، جریان گازی تا دمایی پایین تر از دمای شبنم گوگرد در فشار عملیاتی سرد می شود. پس از آن دمای جریان گازی جهت ورود به بستر کاتالیستی ب...
