Aminotoluic acid, also known as amine-p-carboxybenzoate, is an organic compound that is widely used in the field of raw materials for chemical production. It has a variety of manufacturing methods, and here we will introduce two of the common methods in detail: the chemical synthesis method and the biological fermentation method.
I. Chemical Synthesis Method
Chemical synthesis method is a common manufacturing method of Aminomethylenic Acid, which mainly involves the conversion of raw materials into target products through chemical reactions. The following are the specific steps:
1. Preparation of benzoic acid: Benzoic acid is reacted with sodium hydroxide to form sodium benzoate, this step is to protect the carboxyl group in benzoic acid so that it will not be destroyed in the subsequent reaction.
2. Amination reaction: Sodium benzoate is reacted with ammonia to form ammonium benzoate.
3. Decarboxylation reaction: under heating conditions, ammonium benzoate undergoes a decarboxylation reaction to produce aminotoluic acid.
The advantage of this method is that it can be produced on a large scale with a higher yield. However, the production process produces more waste and puts some pressure on the environment.
II. Bio-fermentation
Bio-fermentation is a more environmentally friendly method of manufacturing aminotoluic acid, in which the raw material is converted into the target product through the action of microorganisms. The following are the specific steps:
1. Cultivation of microorganisms: Select appropriate microbial strains and cultivate them.
2. Raw material input: Benzoic acid is put into the fermenter as a carbon and energy source, and appropriate amount of nutrients such as nitrogen and phosphorus sources are added at the same time.
3. Fermentation process: Microorganisms convert benzoic acid into aminotoluic acid during the fermentation process.
4. Product extraction: the microbial organism is separated from the fermentation broth by centrifugation and filtration, and further extracted and purified to obtain aminotoluic acid.
The advantage of this method is that the production process is more environmentally friendly and less waste. However, more parameters need to be controlled during the fermentation process, and the production process is more complicated.
Both the chemical synthesis method and the biological fermentation method need to be carried out under strict production conditions to ensure the quality and purity of the product. At the same time, the treatment of waste and environmental protection also need to be fully emphasized to promote the green development of chemical production.
In the actual production process, suitable manufacturing methods can be selected according to specific production needs and conditions. With the continuous progress of science and technology, the manufacturing method of aminotoluic acid will be continuously optimized and improved to improve the production efficiency, reduce the environmental pressure, and make greater contributions to the development of the field of raw materials for chemical production.
