A new compound is disclosed having the formula: ##STR1## wherein R is a C.sub.8 to C.sub.22 aliphatic group. The new compound is liquid at ambient temperatures and is useful as an asphalt emulsifier. Also disclosed are asphalt emulsions containing said compound.

Asphalt emulsions comprising N-aliphatic-1,3-diaminopentane emulsifier

Asphalt emulsifying compositions comprising alkoxylated diquaternary ammonium compounds, the cationic portion of the compound preferably including aliphatic radicals containing from about 12 to about 18 carbon atoms. The compounds may be prepared by treating either a diamine or an alkoxylated diamine with an alkylene oxide in a preferred ratio of 1:8. The emulsion most suitably effected by the present compounds will preferably have a size of less than 10 microns.

Alkoxylated diquaternary ammonium compounds

A process for preparing certain quaternary ammonium compositions from tertiary amines selected from the group consisting of tertiary amines containing one or two long-chain aliphatic groups, and mixtures thereof, is disclosed. The process comprises reacting the tertiary amine with dimethyl sulfate, diethyl sulfate, or trimethyl phosphate. The reaction is performed in a reaction medium selected from the group consisting of compounds which have a melting point below about 100.degree. C., preferably are capable of dissolving the desired quaternary ammonium compound, and which contain either (i) an ester linkage derived from a fatty acid, (ii) a primary hydroxyl group, or (iii) both, and mixtures of said compounds. The reaction typically is performed at a temperature between about 50.degree. C. and about 150.degree. C., for a length of time sufficient to convert at least a portion of the tertiary amine to the desired quaternary ammonium compound.
