Inorganic Catalyst For Alkoxylation Of Alcohols

View page
US Patent:
43026133, Nov 24, 1981
Filed:
Aug 22, 1980
Appl. No.:
6/180236
Inventors:
Kang Yang - Ponca City OK
Gerald L. Nield - Ponca City OK
Paul H. Washecheck - Ponca City OK
Assignee:
Conoco Inc. - Ponca City OK
International Classification:
C07C 4103
US Classification:
568618
Abstract:
Strontium and barium-based catalyzed alkoxylation of alcohols of all classes is carried out more rapidly and produces a more peaked reaction product when carried out in the presence of co-catalysts such as calcium oxide, calcium carbide, calcium hydroxide, magnesium metal, magnesium hydroxides, zinc oxide, and aluminum metal.

Alkoxylation Of Cresylic Acids

US Patent:
43768687, Mar 15, 1983
Filed:
Feb 14, 1980
Appl. No.:
6/121351
Inventors:
Gerald L. Nield - Ponca City OK
Kang Yang - Ponca City OK
Paul H. Washecheck - Ponca City OK
Assignee:
Conoco Inc. - Ponca City OK
International Classification:
C07C 5100
C07C 4103
US Classification:
562465
Abstract:
Cresylic acid ethoxylation is catalyzed by basic compounds and salts of alkaline earth metals. Ethoxylates from such reactions have narrow ethylene oxide distributions, lower pour points and lower by-products as compared to alkali base catalyzed ethoxylation. Suitable catalysts include strontium-containing and barium-containing materials. The catalyst also includes co-catalyst combinations using these materials with one or more promoters including polyols, amines, amides, carboxylic acids and phenols. The co-catalyst combinations can be preformed prior to introduction into the reaction mixture.

Ethoxylation With Strontium Bases

US Patent:
42231647, Sep 16, 1980
Filed:
Jul 2, 1979
Appl. No.:
6/054089
Inventors:
Kang Yang - Ponca City OK
Gerald L. Nield - Ponca City OK
Paul H. Washecheck - Ponca City OK
Assignee:
Conoco, Inc. - Ponca City OK
International Classification:
C07C 4102
US Classification:
568618
Abstract:
Basic compounds of strontium catalyzed the ethoxylation of alcohols in the presence of phenol or alkylphenol co-catalyst. Strontium-produced ethoxylates have sharper ethylene oxide distributions, lower free alcohol, lower pour points, and better detergency than the ethoxylates obtained from alkali base catalysis.

Catalyst Removal From Alcohol Alkoxylates

US Patent:
43295150, May 11, 1982
Filed:
Nov 28, 1980
Appl. No.:
6/210994
Inventors:
Kang Yang - Ponca City OK
Gerald L. Nield - Ponca City OK
Paul H. Washecheck - Ponca City OK
Assignee:
Conoco Inc. - Ponca City OK
International Classification:
C07C 4134
US Classification:
568621
Abstract:
Basic compounds of Ba and Sr used in the production of peaked alcohol alkoxylates can be removed from the products by precipitating with some polybasic organic acids. Examples of effective acids include glutaric, diglycolic, adipic, and azelaic acids.

Barium Oxide/Cresylic Acid Catalyzed Ethoxylation

View page
US Patent:
42107644, Jul 1, 1980
Filed:
May 4, 1979
Appl. No.:
6/036273
Inventors:
Kang Yang - Ponca City OK
Gerald L. Nield - Ponca City OK
Paul H. Washecheck - Ponca City OK
Assignee:
Conoco, Inc. - Ponca City OK
International Classification:
C07C 4102
C07C 4110
US Classification:
568618
Abstract:
Cresylic acid (phenol or alkylated phenols) is used to promote barium oxide or hydroxide which is used as an ethoxylation catalyst for the reaction of ethylene oxide and alkanols of all classes. The reaction is carried out at temperatures of from about 150. degree. to about 200. degree. C. to yield the ethoxylated product. The product obtained has a very narrow high adduct distribution with low levels of by-products and unreacted free alcohols. Calcium and magnesium oxides show negligible catalytic effect.

US Patent:
43060935, Dec 15, 1981
Filed:
Jan 24, 1980
Appl. No.:
6/114868
Inventors:
Kang Yang - Ponca City OK
Gerald L. Nield - Ponca City OK
Paul H. Washecheck - Ponca City OK
Assignee:
Conoco Inc. - Ponca City OK
International Classification:
C07C 4103
US Classification:
568618
Abstract:
Strontium-containing materials catalyze the alkoxylation of alcohols. Strontium produced alkoxylates have sharper alkoxylate distributions, lower free alcohols, lower pour points, and better detergency than alkoxylates obtained from alkali base catalysis.
