Polymerization inhibitor
At present, the production of tert butyl hydroquinone both domestically and internationally adopts the tert butylation method of hydroquinone, as shown in Figure 2. According to different classifications of alkylation reagents, it can be divided into tert butyl method, isobutylene method, and MTBE method. Due to the high toxicity of MTBE to human beings and the environment, this method is almost limited to theoretical research in the laboratory and cannot be promoted in industrial applications.
When the tert butanol process encounters bottlenecks, replacing tert butanol with isobutene is a feasible breakthrough direction. Patent [10] discloses a method for preparing 2-tert butylhydroquinone and co producing BHA using isobutene as an alkylation reagent, which has good selectivity and high raw material utilization rate.
Using isobutylene as an alkylation reagent requires a reaction under closed conditions, which can also be catalyzed by strong acids. In a mixed solvent of xylene and ketone, 85% phosphoric acid is used as a catalyst [8], and isobutylene is added to synthesize tert butylhydroquinone. The selectivity of the single tert butylation reaction can reach over 90%. Cationic resin [9] can also serve as a catalyst for this reaction, but the effect is not very ideal.
Product Parameters
Terbutylhydroquinone, is a white or slightly reddish-brown crystalline powder with a very light special fragrance, almost insoluble in water (about 5 per cent), soluble in organic solvents such as ethanol, ethyl acetate, ether and so on.
Product Advantages
Nowadays, as the synthesis cost continues to decrease, the application scope is gradually expanded to petrochemical industry, feed industry, electronic industry, battery industry, etc..
Our company draws on foreign product synthesis guidance, from 1989 to develop the product, in 1992 was applied to the chlor-alkali industry, a complete alternative to similar foreign products, in 1995 the product was approved by the state in the food industry in the legal use of the product so far, gradually recognized by the people of the market usage is increasing day by day!
Packaging and Transportation
Ltd. production of terbutylhydroquinone, using a variety of packaging methods have the international common all-paper drum packaging, specifications of 20kg, 25kg, but also the use of aluminum-plastic film composite sachets have 500g, 1000kg, etc. can fully meet the needs of different customers.
In terms of transportation, the Internet of Things Internet, interconnection, accurate, efficient and convenient, the province 24 hours to reach the domestic 3 days to reach, Asia within 30 days to reach, 60 days to reach the world, the global courier 15 days to reach.
