Processes for preparing conjugated fatty acid products are described wherein (a) a composition which comprises a fatty acid ester having at least two unconjugated, carbon-carbon double bonds is provided; (b) the fatty acid ester is conjugated in the presence of a water-free base; (c) phosphoric acid is added to the conjugated fatty acid ester such that phosphate salts are precipitated; and (d) the precipitated phosphate salts are removed.

Mixtures of vicinal aminoalkanols of the formula ##STR1## wherein R.sub.1 and R.sub.2 are alkyl having from 1 to 21 carbon atoms and the sum of the carbon atoms in R.sub.1 +R.sub.2 is from 6 to 22, A is a member selected from the group consisting of alkylene having from 2 to 6 carbon atoms and methylalkylene having from 3 to 7 carbon atoms, y is an integer from 1 to 3, R.sub.4 and R.sub.5 are members selected from the group consisting of hydrogen, alkyl having from 1 to 4 carbon atoms and hydroxyalkyl having from 2 to 4 carbon atoms, and their salts with organic carboxylic acids, said mixtures having at least two different adjacent chain lengths of ##STR2## in the range of from 8 to 24 carbon atoms with the proviso that the vicinal substituents are distributed statistically; as well as their process of preparation and their application as corrosion inhibitors.

Quaternary ammonium halides in powder or granular form are prepared by reacting tertiary amines and excess alkyl halides in the absence of solvent at elevated temperature and pressure and conducting the hot, pressurized reaction mixture into an area under lower pressure where the excess alkyl halides vaporize and the quaternary ammonium halides are recovered in powder or granular form.
