| | Isopropylmagnesium bromide Usage And Synthesis |
| Chemical Properties | Clear dark brown or dark gray solution | | Uses | Isopropylmagnesium bromide is a Grignard reagent used in organic synthesis, especially for the introduction of iso-propyl group to carbonyl compounds. It is also used as a strong base in aprotic solvent. | | Uses | Grignard reagent in greener solvent, 2-methyltetrahydrofuran (2-MeTHF)
2-Methyltetrahydrofuran (2-MeTHF): A Biomass-Derived Solvent with Broad Application in Organic Chemistry | | General Description | This product, 2.9 M in 2-methyltetrahydrofuran aligns with Safer Solvents and Auxiliaries, Use of Renewable Feedstocks and Inherently Safer Chemistry for Accident Prevention. | | reaction suitability | reaction type: Grignard Reaction | | Synthesis | Nitrogen was replaced 3 times in a 500L reactor, 25.25kg of magnesium balls (0.8cm) were added, 100L of 2-methyltetrahydro was added and the initiator (2-bromopropane Grignard reagent) was 2kg.
furan and initiator (2-bromopropane Grignard reagent) 2kg, heated to 60-65 degrees reflux, slowly at 50-60 degrees dropwise addition of 123kg of 2- bromopropane and 120L of
2-methyltetrahydrofuran mixture, to make a clear and transparent light brown to light gray liquid, dropwise addition is completed .
reflux for 2 hours, acid-base titration concentration of 3.02 mol, reduce the temperature to about 10 degrees Celsius, stationary settlement for 24 hours, a small amount of black suspension
and precipitate deposited at the bottom of the reactor, and no other solid precipitation, the supernatant pressure into the cylinder. |
