Extra-butylhydroquinone
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. Isobutene has higher activity than tert butanol, and its application and promotion prospects are very optimistic.
1.Product Characteristics
Tertiary butylhydroquinone(TBHQ), white or slightly reddish brown crystalline powder, has a very light special fragrance, almost insoluble in water (about 5 per cent), soluble in ethanol, ethyl acetate, ether and other organic solvents.
Tertiary butylhydroquinone has synergistic properties and can be used synergistically with other antioxidants (e.g. BHA, B HT) as well as chelating agents (e.g. citric acid, etc.).
2.Product Advantages
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!
3.Stockpile
The original warehousing TBHQ capacity of Shandong Baishiyi Food Technology Co., Ltd. can reach 300 tons, and we plan to build a new warehouse of 3,000 square feet in 2024 to improve the short of warehousing.
Our guidelines are in order to save working capital, minimize inventory, but in order to match the market demand, try to improve the inventory retention, and now the actual inventory monthly retention of more than 80 tons, product specifications are complete, the type of refinement of the sub-storage, basically meet the needs of the majority of merchants.
