International Classification:

C08J 320

US Classification:

260 4585R

Abstract:

Novel compounds having the formula ##EQU1## WHEREIN N IS AN INTEGER, 0 TO 3 AND Z is selected from bromine or ##EQU2## the proportion of the selected Br-- and RCO. sub. 2 --being such that the weight percent Br in the compound will be in range 20 to 70, the R in the carboxylate group containing from 1 to 17 carbons and being selected from alkyl, cycloalkyl, aryl, and combinations thereof such as alkaryl and aralkyl, the R groups being the same or different. The now preferred compound 1,7-diacetoxy-2,2,6,6-tetra(bromomethyl)-4-oxaheptane (DATBOH) is prepared by reaction of dipentaerythritol, acetic anhydride and anhydrous hydrogen bromide at about 100. degree. C. , extracting with a solvent, treating with an alkaline wash, and recovering the product as a viscous liquid. Alternately, the corresponding hexaacetate can be brominated using hydrogen bromide. The product compounds are useful as flame retardants, for example, for polymers, e. g.

Assignee:

Phillips Petroleum Company - Bartlesville OK

International Classification:

C09K 504

US Classification:

252 67

Abstract:

A refrigeration process is conducted by employing as the refrigerant a mixture of one or more hydrocarbons and one or more halocarbons. The boiling points of the components of the mixture are bracketed in such a manner that the flammability of the mixture is reduced.

Appl. No.:

7/743011

Inventors:

Yulin Wu - Bartlesville OK
Roy A. Gray - Bartlesville OK

Assignee:

Phillips Petroleum Company - Bartlesville OK

International Classification:

B05D 302

US Classification:

4273885

Abstract:

A composition which forms a corrosion-inhibiting film when applied to a metal surface. The composition comprises a low molecular weight polyfunctional polymer formed by polymerizing a vinyl monomer in the presence of a mercaptan chain transfer agent. In one embodiment, the composition comprises a low molecular weight polyfunctional polymer represented by the general formula: ##STR1## wherein M is a repeating vinyl monomer unit, n is from about 2 to about 40, x is from 0 to about 10, y is from 0 to 1, z is from 0 to 1 if y is 0 and 0 if y is 1 and R is hydrogen, an alkyl group, a hydroxy alkyl group or an alkoxy group. A method of treating a metal surface by contacting the metal surface with a composition that forms a corrosion-inhibiting film thereon is also provided. The composition and methods are useful for inhibiting corrosion of downhole metal surfaces present in oil and gas wells.
