What is the preparation method of 1,3-diaminoguanidine hydrochloride?
To make dihydroxyacetone aldehyde anhydride, the method is as follows:
First take an appropriate amount of acetone and place it in a clean reactor. Slowly heat at low temperature, so that the acetone is gradually melted and stabilized at a suitable temperature. Take hydrogen peroxide for the second time, add it to the kettle one by one by slow dripping method, during which the speed and amount of dripping must be controlled, and stir frequently to ensure that the two are mixed evenly. After the drip addition is completed, continue to stir to ensure that it should be stable and orderly.
When the reaction is near the end, use the method of condensation to cool down the contents of the kettle. Then take an appropriate separation apparatus, and use distillation and extraction to separate the generated product and the remaining material. At the beginning of distillation, the volatile material comes out first, and the product is retained at the bottom of the kettle. Then with the suitable extractant, the extraction method is carried out to make the product more pure.
After that, the purified product is taken, put into another purification kettle, and add an appropriate amount of dehydrating agent. With the help of slight heat, the dehydration reaction is smooth, the excess water is removed, and the dihydroxyacetonaldehyde anhydride is gradually formed. After the reaction is completed, the crystal of dihydroxyacetonaldehyde anhydride can be obtained after cooling and crystallization. Finally, by filtering and washing, the impurities are removed, and dried to obtain pure dihydroxyacetonaldehyde anhydride.
This preparation method requires careful control of conditions at each step, such as temperature, dosage, reaction time, etc., to obtain a good product.
What are the precautions for 1,3-diaminoguanidine hydrochloride during storage and transportation?
1% 2C3 + - + diaminonaphthalenesulfonic acid naphthalene acid should be paid attention to when storing and transporting. Its characteristics are special, which is related to the stability and quality of storage and transportation.
The first word for storage should be placed in a cool, dry and well ventilated place. This is because the substance is sensitive to temperature and humidity. If it is in a warm and humid environment, it is easy to cause qualitative change or biochemical reaction, which will damage its quality. For example, in summer, if there is no cooling and dehumidification in the warehouse, the temperature and humidity will rise sharply, and the product may become moist and agglomerate, which will affect subsequent use. And the storage place should be kept away from fire and heat sources. Because diaminonaphthalenesulfonic acid is flammable, it is easy to cause fire and cause serious disasters in case of open flames and hot topics.
Furthermore, it must be placed separately from oxidizers and acids. This is because diaminaphthalenesulfonic acid is chemically active, mixed with other chemicals, or causes violent chemical reactions, such as explosion, combustion, etc., endangering life and property safety.
As for transportation, there are also many precautions. Packaging must be tight to prevent leakage. If the packaging is damaged during transportation and materials leak, it will not only waste resources, pollute the environment, but also cause danger due to the reaction of leaks with external substances. The transportation tool should be clean and dry, and there should be no residual other chemicals to avoid reaction with diaminonaphthalenesulfonic acid. During transportation, the speed should be stable to avoid sudden braking and bumps to prevent the package from being damaged by shock. And the transportation personnel should be familiar with the characteristics of the product and emergency response methods. In case of emergencies, they can deal with it quickly and properly to reduce the damage.
What is the market price range of 1,3-diaminoguanidine hydrochloride?
In today's world, trade and commerce have moved, and the price of things often varies with time, place and quality. In the market price range of dihydroxyacetone diacid, I have studied all the things in detail, and obtained the following feelings.
Dihydroxyacetone diacid, in the field of chemical industry, has a wide range of uses and is an essential product required by various industries. The determination of its price is related to many ends. Looking at the market conditions, the production of raw materials, its abundance, high and low, is the basis of its price. If the raw materials are rich and easy to obtain, the price may be slightly flat; if the raw materials are rare and difficult to harvest, the price will be high.
In addition, the production process also has a heavy impact. The refined and simple process can reduce its consumption, reduce its cost, and make the price close to the people; and the difficult method requires labor and materials, and the price increases.
Furthermore, the supply and demand of the market determines its price. If you need more and less, the price will rise; if you supply too much and need less, the price will fall.
Looking at the current situation, the market price of dihydroxyacetone diacid is about hundreds to thousands of yuan per kilogram in ordinary trade. If it is a high-purity product, you should ask for special requirements, and the price may exceed this. However, this is only a rough estimate. The market conditions are fickle and changing rapidly, and the actual price is still subject to the negotiation and market conditions at that time. When a businessperson deals, he must carefully review all things and weigh the pros and cons before he can get a suitable price and seek his own benefits.
