Solubility measurements and calculations were performed for two mainly used flame retardants,
for hexabromcyclododecane and for tetrabrombisphenyl-A.For the solubility studies different
pressures (200,300,400,and 500 bar) and temperatures (25,40,60,80,and 100 °C) were
investigated.The experimental data were fitted by means of the Chrastil equation.With this
rather simple model the solubility behavior of the solid substances in supercritical carbon dioxide
can be described with high accuracy.
Introduction
In the field of polymer recycling and/or disposal (e.g.,
polymer composites of mass consumer products such as
electronic waste),new techniques are highly required.
Most of the electronic waste contains flame retardants,
mainly halogenated organic substances.In many recycling
processes plastics are incinerated and the formation
of halogenated dibenzodioxins and dibenzofurans
cannot be avoided.One promising way to separate
halogenated flame retardants from polymer matrixes is
the extraction by supercritical fluids such as supercritical
carbon dioxide (SC-CO2).The advantage of this
process is that the polymer as well as the flame
retardant can be recycled,especially advantageous
because flame retardants are relatively high-priced
products.
Before extraction experiments can be started,the
solubility behavior has to be known and up to now only
little data on flame retardants in combination with
supercritical CO2 are available in the literature.1,2 For
this reason solubility data for the two mainly used flame
retardants,for hexabromcyclododecane (HBCD) and for
tetrabrombisphenyl-A (TBBA),were performed in a
wide range of pressures and temperatures

写的都是天书,不知LZ是否能看懂,嘿嘿!

本研究是利用两种主要的阻燃剂,六溴环十二烷和四溴双酚A,在不同的压力（200、300、400、及500巴）和不同的温度下,对其溶解度进行测量和计算,数据是配于‘克拉斯帝’方程计算.通过这种简单的方式,可以很准确地记述这两种固体在超临界二氧化碳中的溶解度.
概述
在聚合物回收和/或处理领域（例：含聚合物复合材料的大众消费产品,如电子垃圾）,新的技术是迫切需要的.大多数电子垃圾都含有阻燃剂,主要是有机氯化物质.在很多回收工艺中,塑料会被焚烧,无法避免的会产生氯化二苯并二恶英及二苯并呋喃.有一种将聚合物基质中的阻燃剂分离出来的不错方法,是通过以超临界流体来提取,例如用超临界二氧化碳（SC-CO2）.这种工艺的好处是聚合物和阻燃剂都能被回收,特别有利的是阻燃剂是高价产品.提取试验开始前需要了解阻燃剂在超临界二氧化碳中的溶解行为,但有关的文献数据十分有限.
1.2 有鉴于此,六溴环十二烷（HBCD）和四溴双酚A（TBBA）这两种阻燃剂的溶解数据的获取必须通过广阔范围的压力和温度进行.
注：您两个阻燃剂名称有笔误.应该是：
hexabromocyclododecane and tetrabromobisphenol-A.
