The present disclosure relates to methods and an apparatus for extracting terpenes and rosin from resinous wood with an agent that comprises, consists or consists essentially of a terpene to thereby extract the rosin and/or terpene fractions from the resinous wood. The apparatus for extracting rosin and/or terpene fractions comprises a treatment chamber for treating the resinous wood with the agent. The treatment chamber is in communication with a distillation chamber for separating the rosin and terpene fractions extracted from the resinous wood.

Provided are processes of preventing or eliminating caking of particulate materials during milling operations. Processes include the addition of an anti-caking additive such as a rosin, abietic acid, fatty acid, or derivative of any of the foregoing to a mill prior to or along with a particulate chemical, and milling the combination. The addition of the anti-caking additive prevents or reduces the amount of caking observed thereby increasing yields and maintaining or enhancing the resulting properties of the milled product.

Recovery times and/or airflow of flexible polyurethane foam is increased by including certain tackifiers in the foam formulation. The tackifiers are formed into an emulsion that includes a polyether containing oxyethylene groups, a nonionic surfactant and certain fumed silica, carbon black or talc particles.
