Abstract
The invention discloses an urotropine production method. The method comprises the following steps: dissolving a glyphosate pesticide byproduct leftover containing formaldehyde, urotropine and paraformaldehyde in water, letting in ammonia gas, gradually heating to 60-80DEG C, controlling the pH value in a range of 9-10, cooling to below 20DEG C, maintaining the temperature constant for 1h, carrying out pumping filtration, and centrifuging to obtain urotropine having a crystal content of 96% or more. The method has the advantages of simplicity, easy operation, and good environmental protection property.
Description
Technical field
The present invention relates to a kind of production method of urotropine.
Background technology
Existing urotropine production method complexity, not easy to operate, yield is low, and environmental pollution is big.
Summary of the invention
The object of the present invention is to provide that a kind of method is easy, easy to operate, the production method of the urotropine of environmental protection.
Technical solution of the present invention is:
A kind of production method of urotropine, it is characterized in that: the glyphosate agricultural chemicals byproduct pin material that will contain formaldehyde, urotropine, Paraformaldehyde 96, use water dissolution, feed ammonia, be warming up to 60 ~ 80 ℃ gradually, control pH9 ~ 10, be cooled to below 20 ℃, be incubated 1 hour, suction filtration, centrifugal gets the urotropine of brilliant content 〉=96%.
The inventive method is easy, easy to operate, the feature of environmental protection is good.
The invention will be further described below in conjunction with embodiment.
Embodiment
