Polyamines asphalt

Amines. Aliphatic mono-, di-, and polyamines derived from fatty and main acids make up this class of surfactants. Primary, secondary, and tertiary monoamines with Qg alkyl or alkenyl chains constitute the bulk of diis class. The products are sold as acetates, naphdienales, or oleates. Principal uses are as ore-flotation agents, corrosion inhibitors, dispersing agents, wetting agents for asphalt, and as intermediates for the production of more highly substituted derivatives... 

Aliphatic amines and polyamines are bases nearly as weak as ammonia. Alkyl amine hydrochlorides are used rarely now in view of the recognised toxicity. They are known in free or salt form as corrosion inhibitors, flotation collectors and adhesion promoters for asphalt coatings. Acylated polyamines are of interest for the amphoteric biocide synthesis. 

These can undergo further reaction through ethoxy-lation or alkylation. The polyamines and their derivatives are employed as flotation agents in mining, as emulsifiers, as adhesive agents for asphalt, and as water-repellant agents.
