  • Catalytic process
    Patent number: 3965177
    Abstract: A catalytic process for preparing novel hydrocarbonaceous polymeric compounds by contacting a first hydrocarbonaceous compound with a second hydrocarbonaceous compound in the presence of a basic nitrogen catalyst in the substantial absence of water. The novel polymeric type materials provided by the process are useful as nonionic surfactants, as biodegradable detergents, as chemical intermediates in the production of anionic detergents, as lubricating oil additives, and as anti-rust and anti-icing additives in fuels.
