Boric Acid → HCID 86739700, compound

Participants

Reaction Steps

Approximately 170 g of 1-(2-hydroxyethyl)-2-heptadecenyl imidazoline, 170 g bis(2-hydroxyethyl) oleylamine, 150 g toluene solvent and 62 g boric acid were heated to reflux in a reactor equipped as described in Example 2. Approximately 47 ml water was removed by azeotropic distillation at temperatures up to 175° C. over a period of about 5 hours. The solvent was removed by azeotropic distillation and the borated product was filtered hot through diatomaceous earth to yield a clean, brown, liquid product. Certain of the mixed borated material was then subjected to testing in a low velocity friction apparatus test described below. Test results are reported in Table 1 below.
