1. An in-situ process for preparing an alkylphenol-aldehyde resin, comprising:
providing an alkylphenol composition comprising:
a butylphenol composition comprising one or more butylphenol compounds, each compound having one or more butyl substituents; and an octylphenol composition comprising one or more octylphenol compounds, each compound having one or more octyl substituents, wherein at least one of the butylphenol composition and the octylphenol composition is a raw alkylphenol composition;
about 7 to about 14 wt % di-tert-alkylphenol; and
at least about 1 wt % phenol; and
reacting, without pre-purifying the raw alkylphenol composition, the alkylphenol composition directly with one or more aldehydes to form an in-situ alkylphenol-aldehyde resin.
