SYNTHESIS OF LIGNIN MODIFIED IN ENHANCING OIL RECOVERY AND CHARACTERIZATION

摘要：

(2, 3epoxypropyl) dimethyl-ammonium chloride (DMAC) was synthesized with N, N -dimethyl dodecylamine and epichlorohy. The lignin surfactant modified（LM） was prepared by the DMAC with lignosulfonate (SL ） .The optimal preparation condition was obtained as follows based on the result of orthogonal experiment: using acetone as the solvent, n (SL):n (DMAC) , 1:1.1, reaction time, 3h, reaction temperature, 55℃, and pH, 12. Target product was systhethized and the nitrogen content of LM reached 2.25％ based on FT-IR spectrum, UV and elementary analysis. The product was acid-resistant and alkali-resistant and had a good chemical stability
