متن کاملThe reaction between wool and phenyl isocyanate.
During some studies on the reactivity of the cystine linkages in wool, it was necessary to find methods for blocking the various polar side chains with minimum degradation of the fibre as a whole, and without introducing any coloration due to the reagent used. Various workers have found that the amino groups of proteins react readily with i8ocyanates in aqueous solution at pH 8 and 00 (Hopkins ...
متن کاملPreparation and Reaction of Carboxylic Acids
The carbon atom of a carboxyl group has a high oxidation state. It is not surprising, therefore, that many of the chemical reactions used for their preparation are oxidations. Such reactions have been discussed in previous sections of this text, and the following diagram summarizes most of these. To review the previous discussion of any of these reaction classes simply click on the number (1 to...
متن کاملDry sampling of gas-phase isocyanates and isocyanate aerosols from thermal degradation of polyurethane.
The performance of a dry sampler, with an impregnated denuder in series with a glass fibre filter, using di-n-butylamine (DBA) for airborne isocyanates (200ml min(-1)) is investigated and compared with an impinger flask with a glass fibre filter in series (1 l min(-1)). An exposure chamber containing 1,6-hexamethylene diisocyanate (HDI), isophorone diisocyanate (IPDI), and 2,4- and 2,6-toluene ...
