摘要
将ε-HNIW分别置于水、甲苯、正丁醚、环己烷和正庚烷中,于70,80,90℃或沸点下加热240 m in,分时试样的FTIR表明,ε-HNIW的晶型转变与溶剂偶极矩有关,在有偶极矩的溶剂(水、甲苯和正丁醚)中加热240 m in后发生晶型转变,而在没有偶极矩的溶剂(环己烷和正庚烷)中加热240 m in后晶型不发生改变。
ε-HNIW was heated at 70 %： ,80 %： ,90 %： or boiling points in five solvents （ water,toluene,n-butyl ether,cyclohexane and heptane） for 240 min, respectively. The FTIR spectra of specimens sampling at different times indicate that polymorph transformation of ε-HNIW is related to dipole moment of solvents. When ε-HNIW was heated at the above temperatures for 240 min in solvents with dipole moments （water, toluene and n-butyl ether）, the polymorph transformation took place,while in those with zero dipole moment （cyclohexane and heptane） under the same conditions, no polymorph transformation occured.
