According to the experimental analysis, it is not difficult to find that the synthesis of this material has the advantages of high efficiency, environmental protection, economic development, and good oxidation resistance. It can play an important role in grease, light fuel oil and other industries.

Foreword

Di-tert-butyl is an important organic substance of cresol, which has excellent oxidation resistance and stability. It is widely used in many fields such as grease, light fuel oil, plastics, plastics and coatings. With the development of industry and people's high attention to environmental protection, it is very important to develop and design efficient, environmental protection and socio-economic synthesis methods. The following describes a method of generating di-tert-butyl cresol and discusses its application in the antioxidant industry.

Materials and methods

The materials and equipment used in the test include: industrial methanol, tert-butyl alcohol, cresol, metal catalyst, etc. The test method and technical scheme are as follows:

Mixing industrial methanol and cresol in a certain proportion, adding a metal catalyst and heating to a certain ambient temperature;

dropping tert-butyl alcohol into the solution of flow 1, keeping constant temperature and reflecting a certain time;

After cooling to room temperature, di-tert-butyl-p-cresol was separated and purified to obtain a commercial product.

During the experiment, the following points should be paid attention to: control the reaction temperature, duration, raw material preparation and other data; ensure that the speed of dropping tert-butanol is symmetrical; prevent the product from oxidizing during the separation and purification process.

Experimental conclusion

The experimental data of di-tert-butyl that may occur during the synthesis of cresol and the experimental process are as follows:

Generation process: mixing industrial methanol (1) and cresol (2) according to a certain proportion, adding metal catalyst (3), heating to a certain ambient temperature (4).; The tert-butyl alcohol (5) is dripped into the solution in the process 1, and the constant temperature is kept to reflect a certain time (6); the di-tert-butyl-p-cresol (7) is cooled to the indoor temperature, and the product (8) is obtained after purification.

Experimental data: unreasonable reaction temperature may lead to chemical reaction speed too fast or too slow, endangering the yield and quality of products; Uneven dropping of tert-butyl alcohol will also lead to incomplete reaction or local overheating, endangering the quality of products; The oxidation reaction in the separation and purification process will reduce the purity of the product.

The experimental conclusions also show that this synthesis method has the following advantages: soft reaction mechanism and resource saving; application of energy-saving metal catalysts to reduce the impact on the environment; high commodity purity and high yield. In addition, as an excellent antioxidant, di-tert-butyl has broad application prospects in grease, light fuel oil and other industries.
