Title: Direct isolation of captopurile
Inventor: NIIRU JII ANDAASON
IPC: C07D207/46
Filed: 1990-11-06
Abstract: A process is disclosed for direct isolation of captopril from a substrate of the formula <CHEM> wherein R is lower alkyl or lower alkoxy. In this process, the substrate is first treated with an aqueous alkali metal hydroxide capable of forming a water-soluble salt of the substrate, wherein the alkali metal hydroxide has a concentration of 4 M or greater. The substrate is then neutralized, preferably with a mineral acid. By this process, captopril may be directly crystallized from an aqueous solution, avoiding the prior art use of organic solvents and zinc treatment to reduce levels of sulfide and disulfide impurities, respectively. In an alternative embodiment, neutralization is carried out by use of a hydrogen-supplying ion exchange resin.

Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To reduce the cost, by eliminating the need to manufacture bus bars of plural kinds corresponding to the number of bulbs and to their arrangement intervals, even if the number and arrangement pitch are different. SOLUTION: When bulb terminal fittings 19 are brought into contact with bulbs by mounting them on terminal-fitting mounting parts and electric wires 41 (bulb interconnecting members) are brought into contact with bulb- intercommunicating contact parts 22 by housing them in a housing space 36, all the bulbs are connected with each other via the bulb terminal fittings 19 and the electric wires 41. When this structure is applied to a multi-bulb luminaire different in the number of bulbs and arrangement intervals, only the length of the electric wires 41 have to be changed. Costs can be reduced in comparison with a case of manufacturing bus bars each integrally formed with a terminal part to contact with a bulb, of plural kinds corresponding to the number of bulbs and their arrangement.
