1,3-phenyldicarboxylic acid
1. ** Properties **: Under normal conditions, it is a white crystalline powder, odorless and has certain stability.
2. ** Melting point **: About 345-347 ° C, the melting point is high, indicating that the intermolecular force is strong and the structure is relatively stable.
3. ** Solubility **: Slightly soluble in water, the solubility is slightly increased in hot water, this is due to the fact that although there are carboxyl groups in its molecules that can form hydrogen bonds with water, the hydrophobic effect of benzene ring limits its dissolution in water; soluble in ethanol, ether and other organic solvents, due to the principle of similar miscibility, its organic structure part has good affinity with organic solvents.
4. ** Chemical properties **: Because it contains carboxyl groups, it has the general properties of carboxylic acids. It can neutralize with bases to generate corresponding carboxylic salts; it can esterify with alcohols catalyzed by concentrated sulfuric acid to form ester compounds; under certain conditions, it can also undergo polycondensation reactions to form polyester polymer compounds.

1. ** Properties **: Appearance is mostly white to light yellow crystalline solid, with a certain gloss.
2. ** Melting point **: Usually at 77-81 ° C, the melting point is lower than that of 1,3-benzene dicarboxylic acid, indicating that the intermolecular force is relatively weak.
3. ** Solubility **: Insoluble in water, because most of its molecules are hydrophobic organic groups; easily soluble in common organic solvents such as toluene, dichloromethane, etc., good solubility makes it easy to separate and react as a reactant or product in organic synthesis reactions.
4. ** Chemical Properties **: The carbonyl group in the molecule has a certain reactivity and can undergo nucleophilic addition reactions, such as reacting with Grignard reagents to generate corresponding alcohols; its ester group can undergo hydrolysis reaction under acidic or alkaline conditions, hydrolysis under acidic conditions to produce carboxylic acids and alcohols, and hydrolysis under alkaline conditions to produce carboxylic salts and alcohols.

What is the production method of 1,3-benzenedisulfonic acid, 4- [ (1,1-dimethylethyl) oxidized imino] methyl) -disodium salt?
1% 2C3-benzene dicarboxylic acid, 4- [ (1,1-dimethylethyl) oxidized imino] methyl-benzophenone, the preparation method of this product is rarely described in detail in ancient books, and now it is speculative method. Please refer to the common way of chemical industry.
To make 1,3-benzene dicarboxylic acid, m-xylene is often used as the starting material. M-xylene is added to a suitable reaction kettle, catalysts such as cobalt and manganese salts, and an appropriate amount of oxygen is added, heated to a suitable degree, and the oxidation reaction is carried out. In this reaction, the methyl group of m-xylene is oxidized to gradually form a carboxyl group, and then 1,3-benzene dicarboxylic acid is obtained. The main point of the reaction is to control the temperature, oxygen and the amount of catalyst. If the temperature is high, the product will decompose easily. If the temperature is low, the reaction will be slow; if there is more oxygen or excessive oxidation, the reaction will not be complete if there is less oxygen.
As for the preparation of 4- [ (1,1-dimethylethyl) oxidized imino] methyl-benzophenone, first take benzophenone and make it react with formaldehyde in an alkaline environment to obtain 4-hydroxymethylbenzophenone. This step requires careful selection of alkali agents, such as sodium hydroxide or sodium carbonate, and control of their concentration and reaction temperature to avoid side reactions. Then, 4-hydroxymethylbenzophenone and tert-butyl hydroxylamine hydrochloride are condensed with the help of a condensing agent such as dicyclohexyl carbodiimide (DCC) to obtain 4- [ (1,1-dimethylethyl) oxidized imino] methyl-benzophenone. During condensation, the choice of solvent is also heavy, and dichloromethane, N, N-dimethylformamide (DMF), etc. are commonly used to facilitate the reaction.
Although this is a general method of chemical synthesis, the actual operation must be adjusted in detail according to the specific equipment, raw materials and environment, in order to obtain satisfactory yield and purity.
What are the precautions for the use of 1,3-benzenedisulfonic acid, 4- [ (1,1-dimethylethyl) oxidized imino] methyl) -disodium salt?
1% 2C3-benzene dicarboxylic acid, 4- [ (1,1-dimethylethylamino) oxidized ethylene] -diphenyl ketone, there are many precautions in the use of this substance.
First, because of its certain chemical activity, when storing, it should be placed in a cool, dry and well-ventilated place, away from fire and heat sources to prevent dangerous chemical reactions. If the storage environment is improper, or its properties are changed, it will affect the use effect and even cause safety accidents.
Second, when using, be sure to take personal protective measures. Appropriate protective gloves should be worn to avoid direct contact with the skin, because it may have irritating and corrosive effects on the skin. At the same time, protective glasses and masks should be worn to prevent their volatiles from entering the eyes and respiratory tract, causing damage to the eyes and respiratory mucosa.
Third, the use site needs to have good ventilation conditions, and it is best to operate in a fume hood. This can discharge volatile harmful gases in time, reduce the concentration of harmful substances in the air, and reduce the health hazards to the operator.
Fourth, the use process should strictly follow the operating procedures. Precise control of the dosage and reaction conditions. Due to changes in the dosage and reaction conditions, or the reaction results do not match expectations, unexpected side reactions may also occur, posing safety risks.
Fifth, after use, the remaining substances and waste should be properly disposed of. It should not be discarded at will. It should be disposed of by appropriate methods in accordance with relevant regulations to prevent environmental pollution.
