Process For The Continuous Preparation Of Organic Monoisocyanates And Polyisocyanates
US Patent:
2006004, Feb 23, 2006
Filed:
Aug 20, 2004
Appl. No.:
10/923561
Inventors:
Joseph Stuart - Baton Rouge LA, US
International Classification:
C07C 263/10
US Classification:
560348000
Abstract:
The invention relates to a process for the continuous preparation of organic isocyanates through the reaction of organic amines with phosgene in the presence of organic solvents under pressure whereby a concentrated phosgene-containing stream is mixed preferentially with an amine-containing stream in a jet mixer to create a combined jet of reacting amine-phosgene mixture, whereby the combined jet is discharged directly into a reactor vessel and the reactor vessel is operated at a temperature above the decomposition temperature of intermediate carbamoyl chloride products which can be formed upon mixing the aforementioned streams, wherein the combined jet is not pre-mixed with bulk reactor contents, wherein the jet mixer provides sufficiently rapid and thorough mixing and thereby enables an initial reaction temperature lower than the bulk reactor vessel temperature, and the combined jet entering the reactor has sufficient momentum to cause entrainment into it of a sufficient quantity of the bulk reactor contents to be rapidly dispersed and reach the bulk reactor temperature.
Coaxial Jet Mixer Nozzle With Protruding Centerbody And Method For Mixing Two Or More Fluid Components
US Patent:
2004000, Jan 15, 2004
Filed:
Jul 9, 2002
Appl. No.:
10/191675
Inventors:
Joseph Stuart - Baton Rouge LA, US
International Classification:
B01F005/04
US Classification:
366/162400
Abstract:
Rapidly and intimately mixing a plurality of fluid substances. A nozzle assembly having a first nozzle comprising a flow duct with a convergent, tapered nozzle tip; one or more additional nozzles comprising a flow duct with a convergent, tapered nozzle tip wherein each subsequent nozzle is disposed coaxially around the preceding nozzle; and a centerbody disposed coaxially in the interior of the first nozzle, protruding beyond the discharge opening of the first nozzle around which an annular jet of liquid flowing in the annular space between the first nozzle and the centerbody is dispersed.
