[[546ar36]] Plesek and Hermanek / Sodium Hydride Its Use In the Laboratory and in Technology♦ £45 or $69 or 54 Euros Postfree-By-Airmail Worldwide ♦ Published by Iliffe Books Ltd, London, 1968; 185 pages, including tables, bond structures, formulae, references and subject index; 17.5 X 25cm; "Very Good+" brown/marble effect/gilt cloth hardback with library ownership stamp on verso of title page and small 5-digit stamp on front flyleaf. *** "Sodium hydride has been known since the year 1878. As a chemical, however, it appeared for the first time on the market as late as about 1937. This substance, originally interesting from the viewpoint of theoretical chemistry only, has become, within a relatively short time, a basic chemical of a new field the chemistry of complex hydrides. Of considerable technological significance also was the discovery that sodium hydride is highly effective in the deoxidation of metal surfaces and in this respect affords one of the most economic procedures. The application of sodium hydride in organic chemistry is highly promising. Although already several hundred successful applications in this field have been published, sodium hydride continues to be a substance almost unknown to chemists. Mentions of its use are so widely scattered in the literature that it is difficult to find them. Even the entry sodium hydride is referred to in the abstract literature only if the entire paper is concerned with this agent. This may be just the reason why sodium hydride has so far been regarded by organic chemists as a mere laboratory curiosity without great significance, although a number of findings were summarized in the reports of Hansleyand Banus, as well as in publications of manufacturers. The outstanding properties of sodium hydride were not recognized immediately. Different opinions as to its efficiency were influenced by the quality of the hydride available to individual experimenters. In particular, the sodium hydride employed at the beginning of the fifties was often relatively coarse-grained and of poor chemical purity and reactivity. Since that time, there have appeared not only uniform fine dispersions of sodium hydride in liquid paraffin, but also a dry pulverous hydride with an extraordinarily large specific surface, either of which is considerably more effective. At present, it is beyond any doubt that sodium hydride has become one of the most useful agents, converting even extremely weak acids into salts, which permits not only their subsequent alkylation or acylation, but also the condensation of substances with activated hydrogen on carbon with most diverse types of carbonyl compounds." *** A decent crisp/clean copy of a scarce item. |

THANK YOU FOR READING THROUGH TODAY'S REVISION OF THIS PAGE HEREWITH OUR CLICKS & MORTAR JOTTINGS FOR THE DAY This page was freshly revised & updated on Saturday 4th. Sept. 2010. The week has ended well with even more sunshine and no more than a few light showers. We are still living in hope of the builder arriving to fix the leaking roof. Mirabile dictu, the insurance company has accepted the claim and has even suggested we bill them for decor damage. A good deal of frantic toing and froing saved the stock. 'Bought a few more transport books in this morning. That section never goes short of male spenders. Freud had it wrong over tunnels; tracked vehicles appears to be the male obsession. Infantile maternal direction ? Oedipus Schmoedipus or what ? Who knows? Who cares anyway? Change of subject. Andrew has taken the day off work to go to Woody's sister's wedding. British clients should note just how beautiful Southport is right now, and no less wonderful when soon the leaves fall and the Aircraft Show begins. ... Taken From Today's Home Page Jottings. |
