Dimethyldistearylammonium
Bromide (DODMAB) is a bentonite modifier with good performance. In this
experiment, 1-Bromooctadecane is the raw material, and completes tertiary
amination and quaternization successively by changing the condition of
experiment. The result is that the productivity can achieve 78.94% in the
synthesis of DODMAB. It has been used in the experiment of bentonite
modification and achieves good results; compared with using trimethylstearylammonium
bromide as the organic modifier, the synthetic organic bentonite has better
performance than the common organic modifier when used in the oil base drilling
fluid of oilfield operation.
