  • Continuous production and reaction of a diazo compound
    Patent number: 9249088
    Abstract: A process for producing a reaction product of a diazo compound, which process comprises: a. continuously supplying to a first reactor a precursor of a diazo compound; a water-miscible solvent; a base and water; b. mixing the precursor of a diazo compound; the water-miscible solvent; the base and water to generate a diazo compound; c. continuously removing from the first reactor, through a hydrophobic membrane, into a second reactor the formed diazo compound; d. continuously removing from the first reactor all reaction products that have not passed into the second reactor; e. continuously supplying to the second reactor a substrate in a non-water-miscible solvent; f. mixing the above components to generate a reaction product of a diazo compound; and g. continuously removing from the second reactor the non-water-miscible solvent and the reaction product of the diazo compound, and apparatus suitable for carrying out such a process.
