Instruction:
Intermediate of organic synthesis and medicine synthesis, which can be used for synthesis of Xike barbital, dyestuff and perfume, and used as soil fumigant in agriculture. They are also used as intermediates for resin modification and flavor synthesis, household chemicals, emulsion modified Chemicalbook agents, silicon products, etc. It has been reported that the polymer, which can polymerize with plasma to form reverse osmosis wax, can be used in airtight manned spaceship, and can also be used as corrosion inhibitor, catalyst and solvent.
Storage method：Store in a cool and ventilated warehouse. Keep away from fire and heat source. The storage temperature should not exceed 37 ℃. The package should be sealed and not in contact with air. It should be stored separately from oxidant and alkali, and avoid mixed storage. It should not be kept for a long time to avoid deterioration. Explosion proof lighting and ventilation facilities are adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area shall be equipped with leakage emergency treatment equipment and suitable storage materials.
Synthetic method：Bromination of allyl alcohol: hydrobromic acid is put into the reaction tank, sulfuric acid and allyl alcohol are added under stirring. After refluxing for 2 hours, the distillate is evaporated when heated to 8 ℃, and the 68-73 ℃ fraction is collected. After washing with water, dehydrate with anhydrous sodium sulfate and filter to obtain allyl bromide.
Bromination of propylene.
Homoallyl alcohol is a very important intermediate in organic synthesis. The main synthesis method is the addition reaction of allyl metal reagents and carbonyl compounds. The commonly used metal allyl compounds are allyl lithium (Mg, Zn, B, in, Si, Sn, Ti), etc, So we use Grignard reagent of allyl to synthesize
Packing: 250kg / drum.
Annual capacity: 1000 tons / year
