In this thesis , organic - montmorillorite ( org - mmt ) was obtained - by an ion - exchange reaction between na + - montmorillorite ( na + - mmt ) and alkyl ammonium bromide , leading to increase the basal spacing of montmorillonite . xrd analysis indicated that alkylammonium ions had already exchanged with na + ions in na - montmorillonite and long alkyl - chains had entered into the gallery of montmorillorite
X -射线衍射( xrd )分析结果表明有机胺阳离子已同蒙脱土中的钠阳离子发生离子交换作用，烷基长链进入蒙脱土层间，导致层间距扩大，并使蒙脱土层间亲水性转变成亲油性。
