Flammability and Explosibility
Notclassified
Synthesis
By taking 2,6-di-tert-butylphenol as the raw material, and then adding sodium nitrite solution dropwise to form an intermediate product of 2,6-di-tert-butyl-4-nitrosophenol solution, with the added Rayon Nickel is used as a catalyst and carbon monoxide is used instead of hydrogen as a reducing agent to overcome hydrogen as a reducing agent. The pressure in the hydrogenation process is high, which is prone to explosion problems. At the same time, iron crystals are added to remove excess carbon monoxide and avoid the effects of carbon monoxide toxicity. The impurities are removed by filtration, and other by-products will not be formed, which can greatly increase the yield of antioxidant 565, and the product purity is high.
Check Digit Verification of cas no
The CAS Registry Mumber 991-84-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 991-84:
(5*9)+(4*9)+(3*1)+(2*8)+(1*4)=104
104 % 10 = 4
So 991-84-4 is a valid CAS Registry Number.

The invention discloses a synthetic method of an antioxidant 565. The antioxidant 565 refers to 4-[4, 6-dioctyl-1, 3, 5-triazine-2-group] amino]-2, 6-di-tert-butylphenol; acid, 2, 6-di-tert-butylphenol and sodium nitrite are added into an organic solvent for nitrification reaction, and 2,6-ditert-butyl-4-nitrosophenol; sodium hydroxide and a reductant are added, and 2,6-ditert-butyl-4-nitrosophenol has a reduction reaction to generate 2,6-di-tert-butyl-4-aminophenol; n-octyl mercaptan reacts with cyanuric chloride under action of a catalyst to generate a 2,4-dioctyl thiol-6-chlorine-1,3,5-triazine compound; 2,6-ditert-butyl-4-nitrosophenol reacts with the 2,4-dioctyl thiol-6-chlorine-1,3,5-triazine compound to generate 4-[4, 6-dioctyl-1, 3, 5-triazine-2-amino]-2, 6-di-tert-butylphenol. Thesynthesis method avoids the use of an expensive hydrogenation catalyst and dangerous high pressure. The reaction condition is mild, operation is simple, the yield is high, the quality of intermediateproducts is good, and the yield and quality of the prepared 4-[4,6-dioctylthio-1,3,5-triazine-2-group] amino] 2,6-di-tert-butylphenol are higher.
