Abstract
Prezenta inventie se refera la o compozitie care consta din 5....7% în greutate acid clorhidric, 1....2% procente în greutate acid-2-hidroxicarbon-1,2,3-propantricarboxilic, 0,3.....0,8% procente în greutate dintr-o sare de polioxietilentetramina alifatica si acid carboxilic alifatic ti 0,02.....2% procente în greutate substanta tensioactiva, în care raportul în greutate a hexametilentetraminei fata de sare de polioxietilenalchilamina si acid carboxilic este de 1 : 1. Compozitia conform inventiei, este utilizata la spalarea sedimentelor care iau nastere la alchilarea izobutanului cu olefine în prezenta acidului fluorhidric.The present invention relates to a composition consisting of 5-7% by weight of hydrochloric acid, 1 to 2% by weight of 2-hydroxy-1,2,3-propanetricarboxylic acid, 0.3. ... 0.8% by weight of an aliphatic polyoxyethylenetetamine salt and aliphatic carboxylic acid of 0.02 ... 2% by weight of the surfactant wherein the weight ratio of hexamethylenetetramine to the salt of polyoxyethylene alkylamine and carboxylic acid is 1: 1. The composition according to the invention is used to wash sediments that give rise to the alkylation of isobutane with olefins in the presence of hydrofluoric acid.
