The concept ofequivalent weightallows you to explore the fact that atoms combine to form molecules in fixed number ratios, not mass ratios. That is, while element masses differ, when it comes to bonding with other atoms, thenumber of atoms, expressed in moles, is the determining factor in h...
PREPARATION OF LOW EQUIVALENT WEIGHT\nAROMATIC POLYETHER POLYOLS OF VARYING REACTIVITYAbstract of the Disclosure\nA method for making amino polyols from a water-soluble\nphenol, ammonia or a primary amine or diamine, a source of\nformaldehyde and alkylene oxides in the presence of water is\n...
This indicates that the decarboxylation route is suppressed, favouring deamination to form ammonia and organic acids. As these acids are more easily gasified than nitrogenous compounds such as amine, the CGE increased in the presence of activated carbon [54]. This could mitigate the negative effects...

For example, one of the commercial forms of acid smells strongly of NOCI, aqua regia; and another liberates ammonia in large quantities when treated with caustic. Aside from other disadvantages these impurities cause the oil to darken in our process. The particle size and density of our tungst...
