Provided herein are isoparaffins derived from hydrocarbon terpenes such as myrcene, ocimene and farnesene, and methods for making the same. In certain variations, the isoparaffins have utility as lubricant base stocks.

Co-extraction techniques for separating and purifying butadiene and isoprene from a C.sub.4 hydrocarbon mixture including butadiene and a C.sub.5 hydrocarbon mixture including isoprene are provided. In an exemplary embodiment, a system includes a dimerization heat exchanger, a C.sub.5 purification column; an extraction zone including a mainwasher column, a rectifier column and an afterwasher column; a distillation zone; a degassing zone; and an isoprene finishing column. The system can further include a C.sub.5 washer column, an absorption column, and a distillation column.

Described herein are pharmaceutical compounds and compositions and methods of making thereof. Methods of synthesis for the compounds are described herein. The compounds or compositions described herein may exhibit aromatase inhibition activity or estrogen receptor activity. The compounds and compositions described herein may be useful in the treatment of a condition in a subject.
