The reaction was heated to 130°C for 2 hours, the reaction was then refluxed at 130°C for 2.5 hours prior to vacuum distillation at 27"Hg vacuum and 130°C.
  • EXAMPLE 13 Preparation of a Mono Adduct of 550Mn Polyisobutene- Substituted o-Cresol and Dimethylamine
  • the polyisobutene-substituted o-Cresol of Example 3 (350g, 0.533mol), dimethylamine at 40% in water (69.65g, 0.633mol), and toluene (114g, solvent) were charged to a round-bottomed flask and heated rapidly to 100°C.
  • Formaldehyde solution 37% by wt solution in water (53.67g, 0.662mol) was then added over 20 minutes via a pressure equalising dropping funnel.
  • reaction was heated to 130°C as azeo distillation allowed, the reaction was then refluxed at 130°C for 2.5 hours prior to vacuum distillation at 27"Hg vacuum and 130°C where HOg of toluene was removed. Analysis revealed 1.6% nitrogen, alkalinity value of 71.4 mgKOH/g.

Abstract

L'invention porte sur une composition détergente contenant un produit de réaction de Mannich d'un phénol (1) à substitution ortho-alkyle à substitution hydrocarbyle ou un mélange du phénol (1) et un phénol (2) à substitution hydrocarbyle, un aldéhyde, et une amine, le phénol (1) étant présent dans le mélange à environ 50 % moles ou plus. Le concentré et les compositions de carburant comprennent la composition détergente. L'invention se rapporte à un procédé de contrôle de dépôts dans un moteur à combustion interne permet de faire fonctionner le moteur avec la composition de carburant, ce qui donne une qualité de détergent incroyablement supérieure.
