Abstract
Derivatii de ditiofosfat de zinc utilizabili ca aditivi antioxidanti pentru uleiuri lubrefiante, conform inventiei, sunt 0,0-dialchil-N-bis-metilen-0,0-dialhilfenilditiofosfat de zinc cu formula generala I: (vezi formula) în care R1 si R2 reprezinta radicali alifatici, identici sau diferiti, cu catena lineara sau ramificata si contin un numar de 3...12 atomi de carbon, iar R3 reprezinta radicali alchilici, identici sau diferiti, care au catena alifatica lineara sau ramificata, alcatuita dintr-un numar de 3...18 atomi de carbon, acesti derivati avînd un continut minim de 5,2% în greutate zinc, minimum 4,8% în greutate fosfor si minimum 9,8% în greutate sulf. Procedeul de preparare a derivatilor conform inventiei, consta în aceea ca 24 parti în greutate dintr-un alcool sau amestec de alcooli, avînd 3...12 atomi de carbon în catena, se aduc în reactie cu 10 parti în greutate pentasulfura de fosfor, în intervalul de temperatura 40...120 degree C, timp de 4...8h, iar separat, 47 parti în greutate alchilfenol avînd 3...18 atomi de carbon în catena alifatica, se aduc în reactie cu 2 parti în greutate formaldehida si 3 parti în greutata solutie amoniacala, timp de 2h, la temperatura de 40...80 degree C, dupa care se îndeparteaza apa sub vid, .....Zinc dithiophosphate derivatives useful as antioxidant additives for lubricating oils according to the invention are zinc 0,0-dialkyl-N-bis-methylene-O, O-diallylphenyldithiophosphate of the general formula I wherein R 1 and R 2 represent aliphatic, identical or different radicals with a linear or branched chain and contain a number of 3 to 12 carbon atoms and R3 represents identical or different alkyl radicals having a straight or branched aliphatic chain consisting of a number of 3 to 18 carbon atoms, these derivatives having a minimum content of 5.2 wt% zinc, at least 4.8 wt% phosphorus and at least 9.8 wt% sulfur. The process for preparing the derivatives according to the invention consists in that 24 parts by weight of an alcohol or mixture of alcohols having from 3 to 12 carbon atoms in the chain are reacted with 10 parts by weight of phosphorus pentasulfide, in the range of 40 ... 120 ° C for 4 ... 8h, and separately 47 parts by weight of alkylphenol having 3 to 18 carbon atoms in the aliphatic chain are reacted with 2 parts by weight formaldehyde and 3 parts by weight ammoniacal solution, for 2h, at 40 ... 80 ° C, after which the water is removed under vacuum, .....
