Abstract
A kind of method of producing potassium-ammonium sulfate compound fertilizer with Repone K and effect of sulfuric acid, be in filling the ammonification jar of the saturated mother liquor of potassium-ammonium sulfate, add sal enixum, add ammonia or bicarbonate of ammonia or volatile salt again and carry out aminating reaction, reaction after whizzer separate, get final product the potassium-ammonium sulfate binary compound fertilizer.Technology of the present invention is simple, and the rate of recovery of potassium reaches 100% in the raw material, the potassium-ammonium sulfate that makes can with phosphate fertilizer, the ternary compound fertilizer of arbitrary proportion is produced in mixing such as urea.The present invention is applicable to newly-built enterprise, is particularly useful for the enterprise of existing production of compound fertilizer ability, existing technology is transformed slightly, with the benefit that obtains at double.
Description
The invention belongs to the method for producing potassium-ammonium sulfate compound fertilizer with Repone K and effect of sulfuric acid.
At present, the production of China's compound fertilizer all is by after producing vitriolate of tartar monobasic fertilizer, itself and nitrogen, phosphate fertilizer etc. is mixed again, and just can obtain binary or ternary compound fertilizer.
Purpose of the present invention provides a kind of chemical reaction that passes through, and directly produces the method for potassium-ammonium sulfate binary compound fertilizer.
Invention is achieved in that in filling the ammonification jar of the saturated mother liquor of potassium-ammonium sulfate, add the sal enixum that makes with Repone K and effect of sulfuric acid, add ammonia or bicarbonate of ammonia or volatile salt again and carry out aminating reaction, after reacting completely, change material over to whizzer and separate, get final product the potassium-ammonium sulfate binary compound fertilizer.Recycling Mother Solution is used.The mol ratio that adds ammonia or bicarbonate of ammonia and sal enixum in the aminating reaction is 1: 1, add carbonic acid ammonia and sal enixum mol ratio be 1: 2.
Describe the present invention in detail below in conjunction with embodiment.
Repone K and sulfuric acid is stand-by by the sal enixum that liquid phase reaction makes in reactor.In filling the ammonification jar of 100 milliliters of saturated mother liquors of potassium-ammonium sulfate, add the sal enixum that 68 grams make with Repone K and effect of sulfuric acid, stir, slowly add 35 milliliters of 25% ammoniacal liquor then, react after 15～30 minutes, material is gone to whizzer separate, can get potassium-ammonium sulfate binary compound fertilizer 76.5 grams.Recycling Mother Solution is used.
Technology of the present invention is simple, and equipment capacity is big, and production cost is low, and the rate of recovery of potassium can reach 100% in the raw material, and the potassium-ammonium sulfate that makes can mix the ternary compound fertilizer of producing arbitrary proportion with phosphate fertilizer, urea etc.The present invention is applicable to newly-built enterprise, is particularly useful for the enterprise of existing production of compound fertilizer ability, existing technology is transformed slightly, with the benefit that obtains at double.
