What is Terephthalaldehyde?
Terephthalaldehyde is an important fine chemical raw material for the lower reaches of the vicrine. Because there are two lively aldehyde base groups in its molecular structure, they can gather or gather with other monomers to form polymer materials, which are mainly used to synthesize fluorescence Materials, catalyst carriers, and other polymer polymers. The traditional production method of phenyl -dizendehyde is to be solved by hydrochloride under the action of nitric acid or metal oxides.
This production process requires a large amount of toxic chlorine, nitrate, and sodium hydroxide, producing gases such as hydrogen chloride, NOX and chloride alkyl, and can easily form environmental pollution and equipment corrosion. Material leakage can also cause damage to the human body. In addition to the traditional chloride method, the synthesis method of phenyl formaldehyde also includes hydrogenation method of phenyl acid (ester), hydrogenation method of benzene, and direct oxidation method to dyshane.
The experimental research on the application promotion and industrial production of benzene two years has gone through more than 20 years. In recent years, with the expansion of its application scope and increased usage, it has formed a fine market potential and strong vitality and strong vitality and strong vitality. For the variety of chemical products, its series of products, dichlorimumine and aldosic acid, have also become certain. The industrial varieties of the scale are mainly used in the production fields of white agents, resin, plastics, pesticides and other production areas; bromine cycloralanes are mainly synthetic production of various organic matter; solid iodine disinfection agents The new type of disinfection agent composed of elements has the characteristics of broad -spectrum, high efficiency, strong sterilization, strong sexual stability, and safety. It is suitable for disinfection, oral, intestinal, urethra, and cervical mucosa disinfection of skin surgery.

Application of Terephthalaldehyde
The fluorescent whitening agent mainly includes two types: di -styrene -based plybonate (such as CBS, etc.) and bisotrazine. ER-I is one of the representative varieties of di-styrene-based phenylphenyrine. Totoids and cyanide chlorine reactions were used to obtain phosphorus and nitrogen-containing aromatically ring intermediates, and then an ER-I reaction with the WITTING reaction with pipylin formaldehyde.
The results of the study showed that the Moore ratio of phosphate and chlorine was 1.1, the feeding temperature was controlled at 140 ° C, the reaction time was 9 h, and the total revenue of the two -step reaction was 93%. Adopt (adjacent cyanoprilis) moltic acid diacerne, (to cyanoprite) radonic acid diacerne, phenyl formaldehyde, and sodium hyamanol synthetic fluorescent whitening agent DX -EB. ) The proportion of dihymes to (neighboring cyanobacter cyisyl) dihydronate is 1.5, and when the reaction temperature is 40 ° C, 1-neighbor-cyanobyrene-4-4 The highest rate is 74.72%.
There is a new type of SBQ photoresal monomer. Specifically, organic base catalysts instead of traditional weak acids and strong acid catalysts, synthetic pyridine seasoning ammonium salt, adding the salt to containing methanol, toluene and benzene formaldehyde, and other organic organic formaldehyde, and other organic organic In the organic alkaline solution of the solvent, the solution is obtained for 5-8 hours of return. The cooling crystals obtain the SBQ monomer with bright yellow purity than 99%. In addition to being used as a fluorescent whitening agent, phenyl formaldehyde can also synthesize fluorescent materials for material testing.
For example, with phenyl formaldehyde and aminophenol as the raw material, the amino phenol recognition unit with complex metal function and the chemical fluorescence sensor of the benzene formaldehyde report unit can detect CU2 + efficiently and highly selectively. It has been successfully applied to the CU2 + concentration in the detection of fresh L929 cells; the use of Rodinming and benzenethatin is used to obtain photovoltaic substances through the reaction of Sidhine. The transition metal has only a slight interference to the spectral spectra. This light -sensitive substance branch is on the surface of the SiO2 nanoparticles, which ensures the repetitiveness of the sensing. It is expected to be further used in optical sensors.
The use of phenyldehyde and sulfidamide as a substrate, and sodium hydroxide as a trigger, synthesized a semiconductor blue fluorescent cypamidazole dye compound. This type of compound can withstand the temperature up to 200 ° C, not only in ultraviolet ultraviolet The wavelength of the area 264 nm is absorbed, and it has a strong absorption spectrum at 485 NM at the visible light zone.
The price band of this type of compound can be 2.56 EV, which is fluorescent in 467 nm and 497 nm. In the future, it may be applied to electronics and optics. The solvent thermal synthesis, normal return and microwave auxiliary are used to obtain a polymer with fluorescence performance. The results show that the sample of 180 ° C solvent synthesis has a better detection of triangular nitrate tactone performance in the soil. The minimum concentration of tritenophyls is 1.8 nmol/L.
The Synthesis Process of Phenylvioxidaldehyde
The chloride hydrolysis is the most traditional way to synthesize the phenyl formaldehyde synthesis process. First, it is to replace the meal group in the second oxyl, and then directly hydrolyze or oxidize the production of benzene -picanne formaldehyde. Among them, the first step of chloride reaction conversion rate is close to complete. The second step of the hydrolysis process is different due to the different income of catalysts. The liquid after hydrolysis needs to be neutralized and filter to obtain a rough benzaldehyde. Generally speaking, in the process of oxidation of vyzylene chloride, in addition to generating target products, there is also by -products such as aldehyde -based phenylic acid.
Take chloribal chloride with two gyrolytic, tetrachloride, puppet nitrogen dietadium and chlorine gas as raw materials and solvents, and then oxidize under catalytic nitrate and zinc nitrate. The addition of zinc nitrite increases The income rate is more than 89%, and the product purity is higher than 99.0%. The chloride hydrolysis method usually uses high toxic chlorine gas, which is very unfriendly to the environment. In order to avoid directly using chlorine gas, the n-fluoribalbenzenesulfonamide and sodium chloride react with the dietne, which is highly selectively synthesized to dichlorobenzhenylene. Incarly phenyldehyde, the sodium hydroxide neutralized and oxide mother liquid, and the heavy crystallization of the ethanol water hybrid solution was obtained from the product of the phenyl formaldehyde.
