International Classification:

C09K 504
C10M10538

US Classification:

252 68

Abstract:

Improved refrigeration lubricants useful in compression refrigeration units are esters, exhibit an excellent balance of performance characteristics, notably in the combination of good miscibility, hydrolytic stablity, wear resistance coupled with a viscosity within the range required in many commercial refrigeration units. These esters are of a hindered dihydric or trihydric alcohol such as trimethylolpentanediol and a fatty acid, where at least 80 number percent of the acyl groups are straight chain groups.

Abstract:

Long chain alkyl substituted naphthalenes are produced by alkylating naphthalene with an olefin or other alkylating agent with at least 6, and usually 12 to 20 carbon atoms, in the presence of an alkylation catalyst comprising a zeolite having both ammonium and protonic species associated with the exchangeable sites of the zeolite. The zeolite is usually a large pore size zeolite such as USY. The presence of both ammonium and protonic species increases selectivity for production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products.
