The application discloses thiol ester molecules and α-hydroxy thiol ester molecules having a thiol group located on one of the final two carbon atoms in a carbon chain or a terminal or α-hydroxyl groups, respectively. The disclosed thiol ester molecules and or α-hydroxyl thiol ester molecules es may be made from unsaturated ester molecules having one or more terminal alkene groups. The disclosed techniques also provide methods for making unsaturated ester molecules having one or more terminal alkene groups by the metathesis of unsaturated esters having one or more internal carbon-carbon double bonds (e.g. natural source oils). The thiol ester molecules or α-hydroxy thiol ester molecule may be used in reactions with isocyanate monomers, epoxide monomer, or material having multiple alkene groups to make sealants, coatings, adhesives, and other products.
本发明揭示了具有巴豆醇基位于碳链的最后两个碳原子之一或具有末端或α-羟基的巴豆醇酯分子和α-羟基巴豆醇酯分子。所述的巴豆醇酯分子或α-羟基巴豆醇酯分子可以由具有一个或多个末端烯烃基团的不饱和酯分子制备而成。本发明还提供了通过不饱和酯类之间的交换反应(例如天然源油)制备具有一个或多个末端烯烃基团的不饱和酯分子的方法。巴豆醇酯分子或α-羟基巴豆醇酯分子可以与异氰酸酯单体,环氧单体或具有多个烯烃基团的材料反应,制备密封剂,涂料,粘合剂和其他产品。
