Why are metals more reactive in acids? Explain what the chemical process of hydrogenation does to fats. Why are amines described as derivatives of ammonia? Explain why most of the salts are soluble in water. Include molecular-level diagrams in the answer. ...
Admixed composition of (1) copolymer of acrylic acids and esters thereof; (2) epoxy compounds; and (3) dicyandiamide After application coatings may be cured by heating, and compositions containing copolymers comprising 2-ethyl-hexyl-acrylate may include curing catalysts such as tertiary amines, fatt...
It appears, however, that they are all phenols containing nitrogen together with the negative radicals of the alcohols and of the acids used. The products can in many cases, be coupled with diazotized aromatic amines to give dyestuffs. In order to more clearly illustrate this invention, the...
The resulting stable isocyanate can then be readily transformed into a variety of amines and amine derivatives including urethanes and ureas. Is HN3 a base or acid? Although NH3 is a weak base, it also acts as a weak acid under certain conditions and reacts with bases. It can lose H+ ...
Increasing produc- tion of fatty acids could serve several purposes: (i) increasing phos- pholipid production to repair damaged bacterial membranes; (ii) utilization of introduced fatty acids or sphingoid bases for phospholipid production (which may or may not be harmful); (iii) competition with ...
