Abstract

The invention discloses a preparation method for an ammonium propionate crystal. The preparation method comprises the following steps: (1) adding propionic acid into a first reactor, a second reactor and a third reactor in sequence, and stirring the propionic acid in the first reactor and the second reactor; (2) performing preheating and pressure stabilizing after liquid ammonia is subjected to evaporation, separation and impurity removal; (3) introducing ammonia gas which is subjected to the preheating and the pressure stabilizing into the first reactor for reaction; (4) cooling and controlling a reaction temperature, and stabilizing pressure; (5) continuously reacting for over one hour, starting the third reactor, cooling and decreasing the temperature; (6) continuously reacting for 2 to 2.5 hours, and measuring the content of the propionic acid in a secondary ammonia exhaust absorption device; (7) stopping introduction of the ammonia gas, and stirring for a suitable time to obtain the ammonium propionate crystal. The invention also discloses a preparation method for ammonium propionate powder. The methods are simple in process, high in efficiency and environment-friendly; the prepared ammonium propionate crystal is high in purity and yield; the ammonium propionate powder is odour-free, corrosion-free, high in palatability and high in efficiency.

Description

technical field [0001] The invention belongs to the field of preparation of chemical raw materials, and in particular relates to a preparation method of ammonium propionate crystal and powder thereof. Background technique [0002] With the rapid development and expansion of the feed industry, feeds are required to have higher quality and freshness, but in the process of production, transportation, storage and feeding, feeds are faced with problems such as uneven feed moisture, exposure to the sun, heavy rain; The influence of climatic conditions such as climate change, typhoon season and frequent and changeable influenza factors lead to mildew and deterioration of feed, which in turn produces toxins and declines in quality. [0003] In order to prevent feed mold, the most economical, simple and effective way is to add feed antifungal agent, but most antifungal agents have more or less disadvantages in application: toxicity, corrosion, odor, affect palatability Sex, cost per...
