Certain solid dye bases which are precursors of acrylic fiber dyes and which contain a tertiary nitrogen atom are effectively quaternized in high yield and purity in a "dry state" quaternization process comprising contacting the dye base with an essentially stoichiometric amount of an alkylating agent at a temperature of 30. degree. -90. degree. C. , said alkylating agent being added to said dye base gradually at a rate such that the reaction mixture is a free-flowing solid throughout the reaction.
Bait Compositions For The Control Of Insects Prepared From Pregel Corn And A Toxicant
Richard B. Balsley - Lebanon NJ Abdel H. Marei - Mercerville NJ
Assignee:
American Cyanamid Co. - Stamford CT
International Classification:
A01N 2500 A01N 4354
US Classification:
424251
Abstract:
There is provided a pesticidal bait composition useful for the control of insects, such as fire ants. There is also provided a method of preparation of said baits, whereby pregel defatted corn grits are blended with a solution of a toxicant in a mixture of an edible oil, such as soyabean oil, and a higher fatty acid, such as oleic or stearic acid.
Calcium And Magnesium Salts Of 4-(2-Hydroxy-1-Naphthylazo)-1-Naphthalenesulfonic Acid For Dyeing Fiberglass
Richard Benjamin Balsley - Lebanon NJ Herbert Soffer - Fanwood NJ Woodrow Wilson Robbins - Bound Brook NJ
Assignee:
American Cyanamid Company - Stamford CT
International Classification:
C09B 2916 D06P 380 C03C 1300
US Classification:
260195
Abstract:
Dyes of the formula: ##STR1## wherein M is a metal selected from calcium and magnesium and provided that where M is calcium the dye is in the beta crystalline form are superior dyes for the dyeing of fiberglass in that they are resistant to crystal growth in dye pastes and recycle process water in the dyeing of fiberglass. Thus, in the spray dyeing of the fiberglass the dyes do not tend to clog the nozzle of the spraying device as do the corresponding salts of monovalent metals, such as the sodium salt.
Polyvalent Metal Salts Of 7-Hydroxy-8-[P-(Phenylazo)Phenylazo]-1,3-Naphthalenedisulfonic Acid For Dyeing Fiberglass
Woodrow Wilson Robbins - Bound Brook NJ Herbert Soffer - Fanwood NJ Richard Benjamin Balsley - Lebanon NJ
Assignee:
American Cyanamid Company - Stamford CT
International Classification:
C09B 4524 C09B 3102 D06P 380
US Classification:
260148
Abstract:
Dyes of the formula: ##STR1## WHEREIN M is a metal selected from the group consisting of calcium, barium, strontium, magnesium, chromium, manganese, iron, cobalt, nickel, copper, and zinc and wherein n is an integer selected from 2 and 3 are superior dyes for the dyeing of fiberglass in that they are resistant to crystal growth in dye pastes and recycle process water in the dyeing of fiberglass thus, in the spray dyeing of the fiberglass the dyes do not tend to clog the nozzle of the spraying device as do the corresponding salts of monovalent metals, such as the disodium and dipotassium salts.
