Film-forming Alamines provide long-lasting corrosion barrier The fatty amines readily accept H + ions to form positively charged cationic salts. For instance: H CH3CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2 Ν · H + OOCCH 3
These amine salts film on metal forming a barrier against corrosive environments. The positively charged nitrogen group is strongly adsorbed on neutral or negative surfaces. The long chain unbranched alkyl group on the nitrogen repels water and permits close pack ing. Amine salts can be made either oil or water soluble. General Mills produces primary, secondary, tertiary amines, fatty diamines and quatern ary ammonium compounds that are useful intermediates. Their high reactivity permits
Η the introduction of specific chain length and degree of unsaturation into the derived prod uct. The wide selection of fatty nitrogens permits varied solubilities, surface activity and biocidal properties. Why not investigate the potentialities of General Mills fatty nitrogens in meeting your own requirements.
