What are the synthesis methods of N- (Carbamoylmethyl) -2-Aminoethanesulfonic Acid
N- (carbamoyl methyl) -2 - aminoethanesulfonic acid, and carboxylic acid (Carboxymethyltaurine), the synthesis method thereof is more than one, and the following methods are described:
One, the method of 2-aminoethanesulfonic acid-chloroacetic acid-based raw materials. 2 - aminoethanesulfonic acid is soluble in a suitable solution, such as water, in a low-quality substance, such as oxidizing pH value to, this can make 2 - aminoethanesulfonic acid of amino group was, increase its nucleality. And, under mixing add chloroacetic acid or the, the reaction degree should be controlled for a certain, usually in the room to 50 ℃, the reaction small. In this reaction, the amino group of 2-aminoethanesulfonic acid is used as the nucleus, and the carboxymethyl group of chloroacetic acid is attacked, and the chlorine is removed to form N- (carbamoyl methyl) -2-aminoethanesulfonic acid. In the reaction, the acidification process is used, and the pH is reduced to neutral or weakly acidic, so that the mixture is precipitated, and then the process of washing, drying, etc. is completed.
Second, the method of using 2-aminoethanesulfonic acid and bromoethyl acetate as the raw material. First, mix the 2-aminoethanesulfonic acid to form a phase and increase its nuclear activity. Ethyl bromoacetate is used for carboxymethylation. In a solution, such as ethanol or acetone, add a reflux. In this case, 2-aminoethanesulfonic acid of aminoethyl bromoacetate of carboxymethyl methyl carboxymethyl carboxymethyl carboxymethyl carboxymethyl carboxymethyl carboxylic acid is substituted and the bromide is removed. The reaction is completed, and the solution is removed by steam, and then the hydrolysis is reversed to make the ester group carboxylic group. A liquid can be added, such as hydrolysis of an oxidized solution, acidification, and precipitation. The reaction is to obtain N - (carbamoyl methyl) -2 - aminoethanesulfonic acid.
Third, the method of 2-aminoethanesulfonic acid-dimethyl carbonate and formaldehyde raw materials. This reaction is a multi-step reverse process. First, formaldehyde 2-aminoethanesulfonic acid is reversed under suitable conditions to form a medium, and dimethyl carbonate is reversed to provide methyl and carbonyl groups to complete the reaction of carbamyl methyl. The reaction needs to control factors such as resistance, reaction and raw material ratio. After the reaction, a series of extraction operations, such as extraction, crystallization, etc., are completed to obtain N - (carbamoyl methyl) -2 -aminoethanesulfonic acid.
The above methods have their own disadvantages. In the synthesis, it is necessary to take into account factors such as raw material availability, cost, and material quality requirements.
What is the price range of N- (Carbamoylmethyl) -2-Aminoethanesulfonic Acid in the market?
In today's market, the price of N- (carbamoyl methyl) -2-aminoethanesulfonic acid is difficult to hide. The change in its price is related to many reasons.
First, the occurrence of this product is different, and the price is also different. If the origin is abundant and the output is wide, the price may be more affordable; if the origin is scarce, the output is meager, and the price will be more expensive.
Second, the supply and demand of the city is the main reason for the price. If there are many people in need, the demand is too much, and the merchant will raise the price; if there are few people in need, the supply exceeds the demand, and the price will drop.
Third, the method of making this product is also related to this. If the production method is exquisite, the cost can be reduced and the price can be cheap; if the production method is difficult and the cost is high, the price will be high.
Fourth, changes in the world situation, such as the regulations of the government and the measures of trade, can also disturb the price. If the government is strict, the price will increase and the price will rise; if the trade is smooth, the source will be sufficient and the price will be stable.
Looking at all kinds of businesses, the price may fluctuate between tens of gold and hundreds of gold per catty. Small shops or sell cheaper to attract customers; big goods, or because of high quality and high price. And when it is in the peak sales season, the price often rises; when it is low, it seems to fall. If you want to know the exact price, you need to consult in detail in the city and compare it with others before you can get it.
