Embodiment 1a
[0028] The invention provides a formic acid acidifier for feed, which is in liquid form and specifically comprises the following components in parts by weight: 30 parts of formic acid, 30 parts of ammonium formate and 9.1 parts of water.
[0029] The carrier used in this embodiment can be one or more mixtures of silica, sodium sulfate, zeolite powder, montmorillonite, sepiolite, bentonite and medical stone. The preferred carrier of this embodiment is two silicon oxide.
[0030] This embodiment also discloses the preparation method of the above-mentioned formic acid acidifier for liquid feed, which specifically includes the following steps:
[0031] S1. Put 51.9 parts of formic acid and 9.1 parts of water, or directly put 61 parts of 85% formic acid into the reactor (the purpose of adding water in the reaction system is to prevent the precipitation of ammonium formate), start stirring, and slowly pass some Liquid ammonia (check the molar ratio of formic acid and ammonium forma...
Embodiment 1b
[0035] Compared with Example 1a, the acidifying agent provided by Example 1b is powder, specifically including the following components by weight: 30 parts of formic acid, 30 parts of ammonium formate, 9.1 parts of water and 30.9 parts of carrier, wherein, 30 parts of formic acid, 30 parts of formic acid A mixture of 30 parts of ammonium and 9.1 parts of water is a liquid acidulant.
[0036] This embodiment also discloses the preparation method of the above-mentioned powder type acidulant, which specifically includes the following steps:
[0037] S1. Put 51.9 parts of formic acid and 9.1 parts of water into the reaction kettle, start stirring, slowly pass some liquid ammonia into the reaction kettle, and open the cooling water to lower the temperature while adding liquid ammonia to the reaction kettle, so as to control the temperature in the reaction kettle Below 70°C, a mixture of formic acid, ammonium formate and water is obtained.
[0038] S2, after adding liquid ammonia, ...
Embodiment 2 and Embodiment 3
[0056] Embodiment 2 includes Embodiment 2a and Embodiment 2b; Embodiment 3 includes Embodiment 3a and Embodiment 3b.
[0057] The parts by weight of the components in Example 2 and Example 3, the molar ratio of formic acid and ammonium formate, and the specific use of the ratio of parts by weight of the liquid acidulant to the carrier are shown in the table below.
