Stabilization of fatty oils and esters with alkyl phenol amine aldehyde condensates

摘要

Biodiesel fuels, renewable diesel fuels and feedstocks to these fuels (derived from plant seed oils or animal fats) are viewed as more environmentally friendly, renewable alternative fuels or supplemental fuels with petroleum-based diesel. Alkyl phenol amine aldehyde condensates improve the stability of biofuels by inhibiting the degradation processes. Alkyl phenylene diamines employed together with alkyl phenol amine aldehyde condensates in the biofuels give synergistically improved stability of the fuels.
