Production Method of Butylhydroxytoluene

(1) Put p-cresol and tert-butanol in a molar ratio of 1:1.1 into the reactor and heat to dissolve. Under the action of catalyst phosphoric acid, react under strong stirring at 65-70°C; after the reaction is completed, the reaction product is first washed with 10% sodium hydroxide solution until it is alkaline, and then washed with water until it is neutral; remove the solvent and recrystallize with ethanol That is the finished product. CH3C6H4OH+(CH3)3COH[H3PO4]→BHT

(2) Pass isobutylene into a mixture of 98% p-cresol and 2% concentrated sulfuric acid, and react at 65-70°C for 5 hours; wash off the acid with hot water at 60°C, and then wash with 10% NaOH and hot water successively until Neutral too rough. Dissolve the crude product in 50% hot ethanol, add 0.5% thiourea, filter while hot, spin dry, and dry to obtain the finished product with a yield of 90%-95%, a purity of 99.5%, and a melting point of >69.5°C.

In the sector, the main in addition to supporting towers are attached in collection. First consist of p-cresol as well as also vehicle driver right into the key tower in addition to the supporting tower, the temperature level of the key tower is handled at 65-80 ° C, and the temperature level of the complementary tower is regulated at 50-70 ° C. The isobutene gas is presented from all-time low of the major tower, and most of it responds with p-cresol generally tower, as well as also the continuing to be component comes out from the top of the major tower as well as gets in lowest level of the corresponding tower to even more respond with p-cresol. The action cycle of the main tower is taken care of within 4-5 hours. When the response mores than, stop the flow of isobutene gas, consist of 20% NaOH solution, as well as bubble with compressed gas. The counteracted alkylated product was split through a distillation column (8 academic plates) to get an unrefined thing. The last is liquified in 95% ethanol, ion-exchanged to get rid of inorganic salts, cooled to 10-20 ° C for formation, divided, in addition to vacuum-dried to acquire a thing with a melting point higher than 69 ° C.
CH3C6H4OH+( CH3) 2C CH2 [H2SO4] → BHT.

Butylhydroxytoluene Selection Principle

The compatibility between plastic polymers and Butylhydroxytoluene is often poor. Usually, the antioxidant is combined with the polymer melt at high temperature, and the antioxidant molecules are compatible in the middle of the polymer molecules when the polymer is solidified. Within the dosage range of the formula, the antioxidant should melt at the processing temperature. Special attention should be paid to the design of the formula, the melting point or upper limit of the melting range of the solid antioxidant and light stabilizer should not be lower than the processing temperature of the plastic polymer.

Plastic products, especially products with a small surface area to volume ratio (or mass ratio), oxidation mainly occurs on the surface of the product, which requires Butylhydroxytoluene to continuously migrate from the interior of the plastic product to the surface of the product to play its role. However, if the migration speed to the surface of the product is too fast and the amount of migration is too large, the antioxidant will volatilize into the environment on the surface of the product, or be lost in other media where the diffusing agent is in contact with the surface of the product. This loss is actually impossible. Avoid, take into account when designing formulations.

When there is a choice of antioxidant varieties, one should choose a variety with a relatively large molecular weight and a moderately high melting point, and the amount of antioxidants used should be determined on the premise of the most severe use environment.

Butylhydroxytoluene should remain stable in plastic materials, have little volatilization loss in the use environment and high temperature processing, do not change color or develop color, do not decompose (except for antioxidants used for processing heat stabilization), and do not mix with other additives Unfavorable chemical reactions occur, do not corrode mechanical equipment, and are not easily extracted by other substances on the surface of the product.

When processing plastic products, the addition of antioxidants may change the viscosity of the resin and the torque of the screw. If there is a large difference between the melting range of the antioxidant and the resin, the phenomenon of anti-oxidant bias flow or screw suppression will occur. When the melting point of Butylhydroxytoluene is 100℃ lower than the processing temperature, the antioxidant should be made into a certain masterbatch first, and then mixed with the resin to process the product, so as to avoid uneven distribution of the antioxidant in the product and a decrease in processing output due to bias flow.

Environment and sanitation
Butylhydroxytoluene should be non-toxic or low-toxic, dust-free or low-dust, have no harmful effect on human body, no harm to animals and plants, and no pollution to air, soil and water system during the processing, manufacturing and use of plastic products. For food packaging boxes, children’s toys, disposable infusions and other plastic products that are in direct or direct contact with the human body, not only antioxidants that have passed the inspection and approval of the US Food and Drug Administration (FDA), or are allowed by the European Community Commission regulations should be used. varieties, and the amount added should be strictly controlled within the maximum allowable limit.
