627-18-9, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 627-18-9, name is 3-Bromopropan-1-ol. This compound has unique chemical properties. The synthetic route is as follows.
Take a 500 mL three-necked flask dried in an oven, equipped with a mechanical stirrer and a thermometer. Add 98% sulfuric acid (50.0 g, 0.5 mol), dichloromethane 60 mL, and cool to -5 to 5 C in an ice salt bath. Fuming nitric acid (33.5g, 0.5mol) was slowly added. Then, 3-bromo-1-propanol (46 g, 0.33 mol) was added dropwise to the mixture, and the reaction medium was stirred at -5 to 5 C for 4 to 5 hours. The mixture was poured into cold water (350 g) maintaining the temperature between -5 and 5 C. After pouring, the organic phase was taken, 80 mL of dichloromethane was added to the aqueous phase, the organic phase was combined, the combined organic phases were washed with water, adjusted to pH = 6-7 by adding 8% sodium hydroxide, washed with brine, organic phase Dry with magnesium sulfate. Dichloromethane was evaporated under reduced pressure to give 3-bromopropyl nitrate (yield compound of formula M) (53.5 g, 88.1%).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 627-18-9, 3-Bromopropan-1-ol.
