外文摘要：A novel multi -SO3H functionalized strong Bronsted acidic ionic liquid has been prepared for the synthesis of biodiesel from rapeseed oil and methanol. The results showed that the novel catalyst was very efficient for the reaction, with excellent water and acid resistant ability. The catalyst could smoothly transform both the rapeseed oil and free fat acid to the biodiesel. Also the novel ionic liquid was insoluble in the organic phase, which made the recycling of the catalyst very convenient. Operational simplicity, low cost of catalyst used, high yields, wide applicability and reusability are the key features of this methodology. The novel catalyst therefore has great potential for use in green processes.
