WebInitially, the 1.0001g of benzil was a yellow powder, and once dissolved in the 5mL dichloromethane and 5mL ethanol, became a clear yellow solution. The later addition of 0.2998g sodium borohydride caused the solution to become cloudy. As the reduction reaction of benzil progressed, the solution became less cloudy. A TLC plate determined … DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products. In this way, an estimated 400,000 tons were produced in the US, Europe, and … See more Dichloromethane (DCM or methylene chloride, methylene bichloride) is an organochlorine compound with the formula CH2Cl2.
