Appl. No.:

6/271542

Inventors:

James F. McCormick - Tempe AZ

Assignee:

Amba Marketing Systems, Inc. - Tempe AZ

International Classification:

D1002

US Classification:

D10 30

US Patent:

60996358, Aug 8, 2000

Filed:

Apr 9, 1999

Appl. No.:

9/289309

Inventors:

Rebecca Lee Rosas - Houston TX
James Michael McCormick - Houston TX

Assignee:

Lonza AG - Basel

International Classification:

C09B 6900
C08K 516

US Classification:

106493

Abstract:

This invention provides a process for forming an acetoacetarylide-based pigment, comprising: (a) reacting a diketene with an amine to form an acetoacetarylide slurry; (b) separating the acetoacetarylide as a solid from the acetoacetarylide slurry; (c) adding the acetoacetarylide solid to a homogenizer; (d) homogenizing the acetoacetarylide in the presence of water and one or more additives to form an acetoacetarylide slurry; (e) pumping the acetoacetarylide slurry to a reaction tank; (f) adding an alkali or alkaline metal base to the slurry; (g) adding an acid to form a precipitate of the acetoacetarylide; and (h) reacting the precipitate with an azo compound, thereby forming a pigment. This invention also includes the pigments and intermediates thereto formed by the above processes.

International Classification:

B01D53/52;53/58

US Classification:

4235741

Abstract:

A method for producing hydrogen and sulfur from a first gaseous mixture containing hydrogen sulfide and ammonia by separating ammonia from the first gaseous mixture to produce a second gaseous mixture containing hydrogen sulfide; combusting a portion of the hydrogen sulfide in the second gaseous mixture to produce a third gaseous mixture containing hydrogen sulfide and sulfur dioxide; heating the ammonia to a temperature of at least 1800. degree. F. to produce a fourth gaseous mixture containing nitrogen and hydrogen; and, combining the third gaseous mixture and the fourth gaseous mixture and passing the combined gaseous mixture to a sulfur recovery process wherein the hydrogen sulfide and sulfur dioxide are recovered as sulfur. The ammonia may be partially oxidized by the use of substoichiometric amounts of oxygen or thermally dissociated.
