Patent number: 5922903Abstract: An arrangement for a falling film type reactor uses corrugated plates to improve the distribution and dispersion of the gaseous reactant into the liquid. Corrugated plates introduce increased turbulence for promoting better distribution and dispersion of the gas. Corrugation angles can be varied to suit the fluid flow properties of the liquid reactant. The reactor arrangement can also include heat transfer channels defined by the corrugated plates in an alternate arrangement of heat transfer channels and gas liquid contacting channels. The corrugations may also be varied to suit the particular heat transfer requirements of the reactions. The corrugated plates are spaced apart in the contacting channels to prevent localized film contact and placed in contact in the heat exchange portion to stabilize the plate elements defining the corrugations.Type: GrantFiled: November 10, 1997Date of Patent: July 13, 1999Assignee: UOP LLCInventor: Peter R. Pujado

Patent number: 5885952Abstract: A detergent base which is obtainable from the reaction of an ethylenically unsaturated sulfonic acid or carboxylic acid or anhydride thereof with a nonionic surfactant of the formulaR.sub.1 --O-(alkylene-O).sub.n.sbsb.1 --R.sub.2 (1)in whichR.sub.1 is C.sub.8 -C.sub.22 alkyl or C.sub.8 -C.sub.18 alkenyl;R.sub.2 is hydrogen, C.sub.1 -C.sub.4 alkyl, a cycloaliphatic radical having at least 6 C atoms or benzyl; andn.sub.1 is a number from 1 to 60;and if appropriate with sugar derivatives.The detergent base has a good calcium-dispersing power, is very stable to electrolytes and heat and has an excellent washing action and anti-redeposition properties. It is therefore suitable for the preparation of powder and liquid detergents.Type: GrantFiled: May 15, 1996Date of Patent: March 23, 1999Assignee: Ciba Specialty Chemicals CorporationInventors: Rolf Kuratli, Claude Eckhardt, Frank Bachmann, Werner Schreiber
