Embodiment 1

[0028] Synthesis of aspartic acid polymer

[0029] M is Na: add polysuccinimide (ie PSl) to a certain amount of water, then add an equimolar amount of solid NaOH to hydrolyze for half an hour, and dry to obtain sodium polyaspartate.

[0030] M is K: the same synthesis method as M is Na, but KOH is used instead of NaOH.

[0031] M is for NH 4 Synthesis of: the same as the synthesis of M for Na, just use NH 4 OH instead of NaOH.

[0032] Physicochemical performance parameters of aspartic acid polymer:

[0033] 1. State: amber liquid

[0034] 2. Polymer molecular weight: M: 2000-8000

[0035] 3. Density (20°C) g / cm: ≥1.05-1.22

[0036] 4. pH: 6.0-10.0

[0037] 1. Biodegradability: ≥65% for 30 days

Embodiment 2

[0039] Mn-SOD, Cu, Zn-SOD were synthesized according to the method disclosed in CN1803812A.

[0040] Physicochemical parameters of simulated SOD compounds:

[0041] 1. State: amber liquid

[0042] 2. SODm enzyme specific activity: ≥4000IU / mg

[0043] 3. Molecular weight: 1000-3000

[0044] 6. pH value (1% aqueous solution): 8.0-10.5

Abstract

The invention relates to an ammonium chloride anti-caking agent and is characterized in that: the invention consists of simulating SOD and aspartic acid polymer, weight ratio of which is 1 / 1000-5 / 1000; the general formula of the simulating SOD is (C8H8O6N2M.XH2O)n), wherein, the M is chosen from Mn, Cu, Zn or any arbitrary combination thereof, the n is 5-7; the chemical general formula of the aspartic acid polymer is (C4H4O3NM)z, wherein, the z is 15-56, the M is chosen from Na, K, NH4+ or any arbitrary combination thereof. The invention also relates to the application of the anti-caking agent in preparing anti-caking ammonium chloride.

Description

technical field [0001] The invention belongs to the field of chemical fertilizer additives, in particular to an ammonium chloride anti-caking agent and its application in the preparation of anti-caking ammonium chloride. Background technique [0002] As we all know, soda ash (Na2CO3) is a basic chemical raw material with a large output, and the annual output of soda ash is about 20 million tons. The production process of soda ash mainly includes three methods: "ammonia-soda method", "combined soda method" and "trona processing"; while the soda ash is produced, the combined soda method also by-produces the same amount of ammonium chloride with high nitrogen content (NH4 4 Cl) product, ammonium chloride is an important industrial raw material and an excellent nitrogen fertilizer. At present, the domestic production of ammonium chloride is about 7 million tons. Ammonium chloride is a chlorine-based nitrogen fertilizer and is a good nitrogen fertilizer with an N content of mo...
