Green cleaning process for preparing orthoformate

The present invention provides a process for manufacturing a green cleaning orthoformate may be used involving chlorine synthetic industrial exhaust byproduct hydrogen chloride, hydrogen chloride in alcoholic solution prepared was slowly added to the reaction system, so that not only reduces the loss caused by the escape of hydrogen cyanide to improve the yield, but also to avoid corrosion of equipment associated with such a huge company producing a byproduct hydrochloric acid, while greatly increasing the hydrogen chloride by-product of economic value added, no waste production, but by-product ammonium chloride, so that the resources rational use, environmentally friendly production process, so this process have a good social benefits.
