Preparation of Surfactants from Waste Oil and Application in Flotation Deinking
摘要
Abstract
Two kinds of surfactants fatty amide propyl dimethyl amine and fatty amide type quaternary ammonium salt could be synthesized bywaste edible vegetable oil (Abbreviation:waste oil).The optimal conditions of synthesizing fatty amido propyl dimethyl amine were obtainedby conditional experiments with temperature of 110℃,time of 2 h,material ratio of 1 ∶ 1.1,conversion rate of 62％;the optimal conditions of synthesizing fatty acid type quaternary ammonium salt using isopropyl alcohol as solvent were determined as the follows:temperature 72℃,time 0.5 h,solvent content 20％,conversion rate 82.7％.This paper verified the deinking effenciencies of these two surfactants for old newspaper,and compared their deinking results with AEO-9 and commercial soap.Results showed that the deinked pulp brightness using these two surfactants separately was superior to AEO-9 and commercial soap,the brightness of the pulp deinked with the mixture of these two surfactants in the ratio of 1:1 could reached to 54.3％,these two surfactants mixed with AEO-9 separately could achieve 6 and 6 percentage points higher brightness than using AEO-9 alone.关键词
