Abstract
Disclosed is a production method of feedstuff enebenzobisoxazole with monovalent cation, which comprises: preparing saturated aqueous solution by adding water to industrial formate, adding aulfuration natrium, mixing and heating to 60-100 DEG C, agitating equably, depositing heavy metal ions in the sollution, filtering the clean liquid, cooling to the room temperature, adding formic acid with the same amount of the formate, agitating equably, centrifugal separating to obtain enebenzobisoxazole crystal, vacuum-drying at 50-70 DEG C to obtain enebenzobisoxazole products. Compared with the prior art, the invention has the advantages that, the enebenzobisoxazole prepared in the invention removes the heavy metal in the material, accords with the feedstuff enebenzobisoxazole specification, is useful as feedstuff additives and other industrial/agricultural production materials; the total yield of the invention can reach 95-98% of the idea value, the material utilization rate is high, the product quality is improved, and production cost is reduced.
Description
Technical field
The present invention relates to the production method of diformate of monovalence cation used for feedstuff.
Background technology
In recent years, diformate is widely used as fodder additives, and intestinal bacteria, Salmonellas etc. are had effect preferably.
The technology of producing diformate at present both at home and abroad is generally " neutralisation ", promptly adds in carbonate or the highly basic and manufacturing with formic acid, and there are shortcomings such as raw material availability is low, the production cycle is long, energy consumption is high, production cost height in this technology.
Also have by formate directly is dissolved in the report that formic acid prepares diformate, obtain the crystallization diformate by reducing temperature or evaporating excessive formic acid.The diformate non-technical diformate that this method adopts, cost is too high, is unsuitable for industrial production.And contain heavy metal in the industrial formate usually, if this method adopts industrial diformate as raw material, then make product use and have certain risk as fodder additives because can't remove heavy metal.
Summary of the invention
Main purpose of the present invention is to overcome the shortcoming of prior art, and the production method of a kind of high yield, oligosaprobic diformate of monovalence cation used for feedstuff is provided.
The present invention adopts following technical scheme: the production method of diformate of monovalence cation used for feedstuff: industrial formate is added water be mixed with saturated aqueous solution, add sodium sulphite, be mixed and heated to 60-100 ℃, stir, make the heavy metal ion precipitation in the solution, filtered while hot goes out clear liquid, be cooled to room temperature, add the formic acid that is complementary with the formate consumption, stir, centrifugation obtains the diformate crystal, and 50-70 ℃ of vacuum-drying obtains the diformate finished product.
Aforementioned formate is a kind of in sodium formiate, potassium formiate, the ammonium formiate, or its combination.
Aforementioned centrifugation obtains diformate crystalline method, at first will add the clear liquid that leaches after the sodium sulphite reaction and be cooled to room temperature, add the formic acid that is complementary with the formate consumption, stir, centrifugation obtains xln diformate and primary crystallization mother liquor, primary crystallization mother liquor vacuum concentration is extremely saturated, put into the crystallizer stirring and be cooled to room temperature, centrifugation obtains xln diformate and secondary crystal mother liquor, with all xln diformate vacuum-drying, obtain the diformate finished product; The secondary crystal mother liquor is sneaked into the primary crystallization mother liquor vacuum concentration of next time producing.
The production method of aforementioned diformate of monovalence cation used for feedstuff, the heavy metal content of industrial formate detects in elder generation before producing, the theoretical value of the sodium sulphite that calculating adds according to detected result, the amount of the sodium sulphite of described adding is the 110-130% of its theoretical value.
The mol ratio of aforementioned formate and formic acid is 1: 0.5-1.5.
By the above-mentioned description of this invention as can be known, compared with prior art, the present invention has following advantage: the diformate that the present invention makes has been removed the heavy metal in the raw material, meets feed diformate specification, can be used as fodder additives, also can be used as the raw material of other industrial and agricultural production; Total recovery of the present invention can reach the 95-98% of theoretical value, and the raw material availability height has improved quality product simultaneously, has reduced production cost.
Embodiment
The specific embodiment of the present invention, the feed production method of the Potassium hydrogen diformate of monovalent cation:
Extract the heavy metal content that detects industrial potassium formiate before producing earlier, calculate the amount of the sodium sulphite that adds according to detected result; Take by weighing industrial potassium formiate 100kg, add water 50kg, processing industry is with sodium sulphite 0.01-0.1kg (occurrence is the 110-130% with the amount of detected heavy metal complete reaction), thorough mixing, be heated to 80-90 ℃, stir, the filtered while hot waste is got clear liquor and is cooled to room temperature, adds 60 kilograms in formic acid, stir, centrifugation obtains xln diformate and primary crystallization mother liquor, and primary crystallization mother liquor vacuum concentration is put into the crystallizer stirring and is cooled to room temperature to saturated, centrifugation obtains xln Potassium hydrogen diformate and secondary crystal mother liquor, and the secondary crystal mother liquor is sneaked into the primary crystallization mother liquor vacuum concentration of next time producing.All xln Potassium hydrogen diformates place Vacuumdrier 50-70 ℃ of vacuum-drying to water content less than 1%, cooling back is taken out packing and is the finished product Potassium hydrogen diformate.The total recovery of present method can reach the 95-98% of theoretical value, the Potassium hydrogen diformate place to go that present method makes the heavy metal in the raw material, meet the Potassium hydrogen diformate specification that feed is used, can be used as fodder additives, also can be used as the raw material of other industrial and agricultural production.
Certainly, present embodiment has only been introduced the production method of Potassium hydrogen diformate, and the production method and the present embodiment of sodium diformate, dioctyl phthalate ammonium and three's combination are similar.
Above-mentioned only is a specific embodiment of the present invention, but design concept of the present invention is not limited thereto, and allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should belong to the behavior of invading protection domain of the present invention.
