Opioid Analgesics: Chemistry and Receptors

The speedily burgeoning study of the prior 20 years on agonist-antagonist analgesics and opioid receptors makes this exhaustive overview of opioid anal­ gesics quite appropriate and well timed. After an introductory bankruptcy the extra 12 chapters commence logically with morphine and congeners (4- epoxymorphinans) and finish with opioid receptors.

Licensor: Davy Process Technology, UK. � � ������������� ������� Ethylbenzene Application: Advanced technology to produce high-purity ethylbenzene (EB) alkylating benzene with ethylene using patented catalytic distillation (CD) technology. The CDTECH EB process uses a specially formulated zeolite alkylation catalyst packaged in a proprietary CD structure. The process is able to handle a wide range in ethylene feed composition—from 10% to 100% ethylene.

Raw butadiene is purified to meet specifications in the purification section (4). Heavy ends (C4 acetylenes) are also separated in the stripper system (3) as a side product and further processed in the heavy-ends stripping section (5). The solvent recovery step (6) maintains solvent quality and recovers solvent from various product streams. Use of acetonitrile is advantageous to other solvent systems for a number of reasons. ACN’s lower boiling point results in lower operating temperatures resulting in low fouling rates and long run-lengths.

This product will meet all butadiene derivative requirements with typical specifications shown below. �������������� ������� ��������� ������ Description: This butadiene extraction process was originally developed by Shell Chemicals. It is offered under license agreement by Kellogg Brown & Root, who has updated and optimized the process to reduce capital and operating costs. The process scheme consists of contacting mixed-C4 feed with lean solvent in the extractive distillation column (1). The raffinate, butenes and butanes, which are not absorbed, flow overhead to the wash column (2) for solvent recovery.
