摘要

聚乙烯是最大的合成塑料产品，其化学惰性导致难以降解.最近，黄正、管志斌等报道了交叉烷烃复分解方式进行的聚乙烯温和可控降解.使用价廉量大的低碳烷烃（如石油醚）作为反应试剂和溶剂，不同类型的聚乙烯均可实现降解.并且可以通过催化剂和反应的时间的调控，选择性生成燃油或聚乙烯蜡.

Abstract

Polyethylene is the largest-volume synthetic plastic

and its chemical inertness makes it difficult to degrade. Recently

Zheng Huang

Zhibin Guan and coworkers reported a tandem catalytic cross alkane metathesis method for highly efficient degradation of polyethylenes under mild conditions. With the use of widely available

low-value

short alkanes (such as petroleum ethers) as cross metathesis partners

different types of polyethylenes undergo complete conversion into useful liquid fuels and waxes. In addition

the degradation product distribution (liquid fuels versus waxes) can be controlled by the catalyst structure and reaction time.
