Abstract


Three-quarters of the available part of the traditional distillation process is difficult to achieve its reuse in the large-scale industrialized production of long-chain aliphatic amines of high boiling residue . Through the introduction of high-tech separation technology and equipment - molecular distillation technology , effective solution to the thorny problem of the high boiling components is difficult to separate the useful components . This thesis is explored in detail the four main parameters of the molecular distillation process : distillation temperature , operating pressure , the temperature of the feed and the feed rate , the rotor ( blade) speed optimization process and programs in the long-chain aliphatic amines with high boiling point ; methylation reaction with molecular distillation matching , quaternization reaction , complex process optimization . These optimized process constitute a complete valid reuse highboils solutions of long chain aliphatic amine byproduct . After a small scale and expand the trial to determine the industrial design program . And analysis of the costs and economic benefits of the program as a whole .
