Description
Technical field
The present invention relates to allantoins, and in particular, to it is a kind of as allantoin production waste liquid made from compound fertilizer and its system
Preparation Method.
Background technique
Allantoin, English name Allantion, chemical name Allantio are a kind of heavy
The fine chemical product wanted, purposes are extremely wide.Allantoin, which has, promotes skin epithelial cell growth, wound healing, analgesic, soft
Change the physiological functions such as keratoprotein, and it is nontoxic, non-stimulated, without anaphylaxis, be protected from light, sterilization and anticorrosion, antioxidation, can make
Skin keeps moisture content, moistens and soft, thus is widely used in medicine and Cosmetic Manufacture.In addition, allantoin also has thorn
The function of swashing biological growth, can be used as plant growth regulator in agricultural production, there is solid fruit, accelerate the ripening, increase production and other effects.
Natural allantoin is present in the excreta and some plants of certain animals, can be mentioned using certain technique
It takes, for example, Chinese patent CN1958575A and CN1861581A are reported respectively from Chinese yam and extracting allantoin in Herba Cistanches,
But the problems such as complicated because of the low processing step with involved in of content, almost without practical value for the preparation of allantoin.Therefore,
Being all made of chemical synthesis process both at home and abroad prepares allantoin at present.
Existing industrialized production allantoin method mainly uses glyoxal nitric acid oxidation method.Glyoxal method is in two steps
It carries out, it is glyoxalic acid that the first step, which relates to glyoxal through nitric acid oxidation, and second step is under the nitric acid effect of carbon monoxide-olefin polymeric
Glyoxalic acid and urea condensation generate allantoin, yield generally about 40%.It can be seen that glyoxal nitric acid oxidation method produces allantoin
During, a large amount of nitric acid is contained in the waste water of generation, on the one hand the discharge of nitric acid can cause environment greatly to pollute,
The loss of N resource also forms the waste of resource simultaneously.
