  The reaction of condensation of furfural with mercaptoacetic acid esters

  摘要：

  The condensation reaction of furfural with various mercaptoacetic acid esters was studied. The reaction products were tested for their corrosion protective properties in M-16 cylinder oil used for marine diesel engines. It was found that the resulting 2-di(alkoxycarbonylmethylthio)methylfuranes at 2% concentration completely suppress corrosion of lead plates.

  The combination of one or more conventional antimony - or bismuth-containing heat stabilizers with certain aromatic esters or aryloxides containing boron, phosphorus, silicon, antimony, tin or zinc interacts synergistically to provide an unexpectedly high level of heat stability to halogen-containing polymers or resins such as polyvinyl chloride (PVC). In addition the aromatic ester or aryloxide inhibits spontaneous degradation of the stabilizing component in the presence of heat and/or light.

  将一种或多种传统的含锑或铋的热稳定剂与某些含硼、磷、硅、锑、锡或锌的芳香族酯或芳基氧化物结合使用，可产生协同作用，为聚氯乙烯（PVC）等含卤聚合物或树脂提供意想不到的高热稳定性。此外，芳香族酯或芳基氧化物还能抑制稳定组分在热和/或光的作用下自发降解。
