| titleOfInvention | A kind of natural theine production method |
| abstract | The present invention relates to a kind of natural theine production method, current, domestic and international theophylline refines the immersion pyrogenic distillation all adopting west, high pressure absorbs, and its content of caffeine only has about 65%, and not only content is low for it, but also a large amount of use chloroform compounds, there is chemosynthesis.This product it be mainly used as medicine, foodstuff additive, harmful like this, belong to World Health Organization's limits product, and the present invention adopts roasting distillation coacervation, the physical property of cold reaction principle is gathered, through decomposing skinning, removal of contamination by high temperature evaporation effect and material, collect needle-like crystal, complete theophylline work in-process and produce.Adopt low temperature anti-oxidation condensation collecting method, to be heated refinements by constant-temperature high-pressure, high temperature, carry out cold filtration, divide stain look of leaving away, improve the purity of theophylline, check the purity of this product to reach the international highest level of 98.2%-99.92% through national feeler mechanism.This product is widely used in the additive of food, medicine, healthcare products and filed of daily-use chemical industry.This project belongs to deep processing of farm products technology, and it is applied widely, and use value is high, and effects of energy conservation and environmental protection is good. |
