METHOD AND PROPELLER MIXER FOR MIXING TWO COMPONENTS REACTING VIOLENTLY WITH EACH OTHER

A method for intimately admixing two chemically-reactive liquid components comprises introducing one component in the form of a fan shaped spray into a cylindrical mixing chamber 14 and causing this spray to intersect with twin fan-shaped sprays of the second component which latter sprays are introd...

Zusammenfassung:	A method for intimately admixing two chemically-reactive liquid components comprises introducing one component in the form of a fan shaped spray into a cylindrical mixing chamber 14 and causing this spray to intersect with twin fan-shaped sprays of the second component which latter sprays are introduced into the mixing chamber from preferably diametrically opposed locations 24, 26 in a direction substantially perpendicular to the direction of the first component spray. In examples, the components contacted are polyamines and phosgene to produce isocyanates, and acidic aniline solution and aqueous formaldehyde to produce methylene bridged polyphenyl polyamides.
