摘要:
Tertiary alkyl phosphorodichloridites, characterized by the formula: ##STR1## where R.sup.1, R.sup.2 and R.sup.3 may be alkyl having from about 1 to about 4 carbon atoms, aryl having from about 6 to about 8 carbon atoms, or aralkyl having from about 7 to about 10 carbon atoms, however, at least one of R.sup.1, R.sup.2 and R.sup.3 must be alkyl, as new compounds, and synthesis thereof by reacting, at temperatures of 0.degree. C or less, a tertiary alcohol, a tertiary amine scavenger, and phosphorus trichloride, the PCl.sub.3 being employed in amounts in excess of the stoichiometric amount needed to react with the alcohol are provided. Both chlorines of the tertiary alkylphosphorodichloridites so produced may be relaced by RX.sup.- groups from alcohols (ROH), thiols (RSH), or amines (RR.sup.6 NH) in order that trisubstituted phosphite compounds of the formula: ##STR2## are produced. Disubstituted phosphorus acids of the formula: ##STR3## may be produced by heating the trisubstituted phosphite compounds. The RX.sup.- groups are retained as the substituents of the phosphorus acid compounds. Such phosphorus acids are extremely useful in lubricating media as antiwear agents, in insecticides and as additives in rubber.

摘要:
There are provided polymeric pyrrolidinium methanesulfonate viscosifiers which are useful in chemical waterflooding and in drilling fluids. These compounds may be formed by an unexpected cyclization reaction of quaternary diallyl amino groups on polymeric backbones involving the reaction of such groups with bisulfite salts.

摘要:
Lubricating oils which in aqueous media are highly useful as, for example, hydraulic fluids, are provided having improved hard water stability characteristics when oil soluble alkylphenoxypolyethoxylated sulfonates are added thereto.
摘要:
A method for determining the concentration of a brine tolerant sulfonate surfactant in a complex mixture containing, in addition to said brine tolerant sulfonate surfactant, lignosulfonates, crude oil, salts, and water and, optionally, petroleum sulfonates and alcohols, that comprises incorporating into the brine tolerant sulfonate surfactant molecule a small amount of deuterium prior to addition to the complex mixture and determining the concentration of the brine tolerant sulfonate surfactant by measuring its infrared absorption at 2150 cm.sup.-1.
摘要:
Certain new adducts of benzotriazole and oxazolines are provided in which the oxazolines may contain alkyl, alkenyl or cycloalkyl radicals of from 6 to about 20 carbon atoms. Lubricant compositions are also provided having excellent anticorrosion characteristics when minor amounts of such adducts are added thereto.
