Molybdenum dialkyldithiocarbamate compositions and lubricating compositions containing the same
View Patent ↗A novel molybdenum dithiocarbamate composition is produced by preparing a di-tridecylamine (DTDA) intermediate from a butylene feedstock comprising greater than 50% 2-butylene, and preparing a molybdenum dithiocarbamate composition from the DTDA intermediate. The resulting molybdenum dithiocarbamate composition are according to formula (1), wherein R 1 to R 4 are C 11 -C 14 isoalkyl groups, and X represents oxygen and/or sulfur atoms, and R 1 to R 4 comprise, on average, greater than 98% C 13 :
1. A method for producing a molybdenum dithiocarbamate composition, comprising the steps of:
preparing a di-tridecylamine (DTDA) intermediate from a butylene feedstock comprising greater than 50% 2-butylene, and
preparing a molybdenum dithiocarbamate composition from the DTDA intermediate.
2. The method of claim 1 , wherein the butylene feedstock further comprises 1-butylene and isobutylene.
3. The method of claim 2 , wherein the butylene feedstock comprises about 70% 2-butylene, about 20% 1-butylene and about 10% isobutylene.
4. The method of claim 3 , wherein the molybdenum dithiocarbamate composition has, on average, greater than 98% C 13 as part of the substituent alkyl groups.
5. A method for preparing a lubricating composition, comprising the steps of:
preparing a di-tridecylamine (DTDA) intermediate from a butylene feedstock comprising greater than 50% 2-butylene,
preparing a molybdenum dithiocarbamate composition from the DTDA intermediate, and
adding the molybdenum dithiocarbamate to a lubricating base at 0.01-3% of the lubricating composition.
