Multifunctional additives having a variety of advantageous properties are described. They are formed by a process which comprises heating concurrently or in any sequence a) an oil-soluble ashless dispersant containing basic nitrogen with b) an alkoxylated alcohol of at least 8 carbon atoms c) a borating agent and optionally d) an inorganic oxyacid or anhydride of phosphorous. The reactants are in proportions on an active ingredient basis of about 0.03 to about 0.35 part by weight of b) per part by weight of a), and about 0.005 to about 0.06 part by weight of boron as c) per part by weight of a). The reaction temperature can range from about 50.degree. to about 150.degree. C. Water and/or solids present in the resultant mixture can be removed. Preferably, the optional phosphorous component is used in the formation of these additives. This phosphorous component can be an inorganic oxyacid or anhydride of phosphorous.

Lubricant additive compositions

A fuel additive concentrate package comprising a detergent/dispersant, an organic nitrate combustion improver, and a corrosion inhibitor comprising dimer and/or trimer acid is provided enhanced shelf life stability by treating the concentrate with a shelf life stability amount, for example 1,500 and 10,000 ppm, respectively of acid selected from the group consisting of nitric acid/hydrochloric acid.

Fuel additive concentrate with enhanced storage stability

A refrigeration lubricant suitable for use with R-134a-type refrigerants comprises at least one dialkanolamine diester-amide oil corresponding to one of the formulas: ##STR1## in which formulas R is a hydrocarbylene group containing 1-10 carbons; n represents zero or one; each R' is independently selected from alkylene groups containing 1-10 carbons; R' is hydrogen or a hydrocarbyl group containing 1-10 carbons; and each G, when not linked with another G, is independently selected from hydrocarbyl groups containing 1-10 carbons or, when linked with another G, is a hydrocarbylene group which, together with the colinked G, forms a hydrocarbylene group containing 1-10 carbons.

Process for preparing transition metal cyclopentadienyl carbonyl

Cyclopentadienyl manganese tricarbonyl compounds are made by reacting a mixture of 0.25-0.55 moles of manganese acetate and 0.45-0.55 moles of a bis-cyclopentadienyl manganese compound with about 0.5-2.1 moles of an alkyl aluminum compound (e.g. triethyl aluminum) in the presence of about 0.75-1.25 moles of an ether per mole of said alkyl aluminum compound and reacting the mixture with carbon monoxide at about 65.degree.-175.degree. C. and 300-1500 psig.
