Propanoic acid,ammonium salt - Preparation Method of ammonium propionate crystal and powder thereof
from Baidu Library
Application (patent) number:
CN201510770377.X
application date:
2015-11-12
Public/Announcement Number:
CN106699544A
Public/announcement date:
2017.05.24
applicant (patent):
Lu Hao
inventor:
National and provincial code:
CN440305
Abstract:
The invention discloses a preparation method of ammonium propionate crystal, which comprises the following steps: 1) Adding propionic acid into a first reactor, a second reactor, a third reactor, the propionic acid in the first reactor and the second reactor is stirred; 2) the liquid ammonia is evaporated to remove impurities and then preheated and stabilized; 3) ammonia gas after preheating and pressure stabilization is passed into the first reactor for reaction; 4) cooling to control the reaction temperature and pressure stabilization; 5) continuously react for more than 1H, start the third reactor and cool down; 6) the ammonium propionate content in the secondary ammonia tail gas absorption device was measured after the reaction was continued for 2H to 2.5H; 7) the ammonia gas was stopped and stirred for an appropriate time to obtain ammonium propionate crystals. Also disclosed is a preparation method of ammonium propionate powder, which is simple in process, high in efficiency and environmental protection. The prepared ammonium propionate Crystal has high purity and yield, and the ammonium propionate powder has no odor, no corrosion and good palatability, high efficiency.

Propanoic acid,ammonium salt - Reference Information
| LogP | 0.251 at 20℃ and pH8 |
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | ammonium propionate is light yellow liquid, easy to absorb moisture, soluble in water and ethanol. |
| Use | ammonium propionate can be used as a preservative and fungicide. Free propionic acid is produced under acidic conditions and has an antibacterial effect. The lower the pH value, the better the antiseptic effect. Ammonium propionate corrosion is small, for grain anti-mildew and anti-caking effect is good. Feed and Grain preservatives in the United States mainly use ammonium propionate, the use of propionic acid and ammonium propionate compound, in acidic environment can play the best mold, sterilization effect. |
| preparation | ammonium propionate is extremely hygroscopic, deliquescent in humid air. Produced by the reaction of propionic acid and ammonia. |
