Accordingly, the reaction of the algae oil with sulfur was evaluated for production of novel sulfur polymers (through reaction with unsaturated triglycerides) with concomitant enrichment of unreacted saturated triglycerides. Accordingly, the algae oil (409 mg) was first pre-heated to 170 ºC before an equal mass of elemental sulfur was added portionwise over 5 minutes. The reaction was stirred for 30-35 minutes, after which time the reaction mixture became increasingly viscous. After an additional 10 minutes of reaction time, the mixture was cooled to room temperature to provide a brown solid. Unreacted oil was extracted by stirring with ethanol at 50 ºC for 2 hours. The solid material was then isolated by filtration (458 mg recovered) and the filtrate was concentrated under reduced pressure to provide the unreacted oil (146 mg).
