Embodiment 1

[0016] Add 443kg (5.09mol) of n-butyric acid and 400kg of water into the 2000L reaction kettle in turn, raise the temperature to 50°C, slowly add 285kg (2.69mol) of sodium carbonate, keep warm at 80°C for 1 to 1.5 hours, then add 18kg (0.21mol) Stir with sodium bicarbonate, control the pH value of the reaction end point to 8.0, transfer the reaction solution to another reaction kettle for vacuum distillation, and perform drying, crushing and blending in sequence to obtain the product. The product is in accordance with the national standard of feed additive sodium butyrate After testing, it is packaged and put into storage.

Embodiment 2

[0018] Add 443kg (5.09mol) of n-butyric acid and 400kg of water into a 2000L reaction kettle in sequence, raise the temperature to 50°C, slowly add 185kg (4.63mol) of sodium hydroxide, keep warm at 80°C for 1 to 1.5 hours, then add 20kg (0.24mol ) stirring with sodium bicarbonate, control the pH value of the reaction end point to 8.0, transfer the reaction solution to another reaction kettle for distillation under reduced pressure, and perform drying, crushing and blending in sequence to obtain the product. The product is based on the feed additive sodium butyrate After the national standard inspection, it is packaged and put into storage.

Abstract

The invention discloses a preparation method of feed additive sodium butyrate, which comprises the following steps: after dissolving n-butyric acid in water, heating to 50 DEG C, adding sodium carbonate or sodium hydroxide, keeping the temperature at 80 DEG C for 1-1.5 hours, adding sodium bicarbonate, stirring, controlling the pH value of the reaction end point at 8.0-10.0, distilling under reduced pressure and drying to obtain the sodium butyrate. The sodium bicarbonate is added in the reaction process to regulate the pH value of the neutralization reaction between the butyric acid and the sodium carbonate or sodium hydroxide, so that the pH value is stable in the reaction process, thereby enhancing the product quality.

Description

technical field [0001] The invention relates to a preparation method of a feed additive, in particular to a preparation method of the feed additive sodium butyrate. Background technique [0002] Feed additive sodium butyrate is mainly used in the field of animal nutrition and health care. It is a direct energy source for animal intestinal epithelial cells, which can enhance feed attraction, increase feed intake, and improve animal growth performance. It is a functional feed additive. The history of using sodium butyrate in feed in European countries can be traced back to the early 1990s, and the relevant regulations are detailed in EU Regulation No. 1831 / 2003. The domestic feed industry gradually began to use sodium butyrate after 2000. After being included in the feed additive category catalog in the Ministry of Agriculture Announcement No. 318 (2003) of the People's Republic of China in 2003, sodium butyrate was rapidly popularized and applied. [0003] Sodium butyrate is...
