The solid-state intercalation of organoclays, by using surfactants bromide salts (n-C12H25(CH3)3NBr, n-C14H29(CH3)3NBr, n-C16H33(CH3)3NBr and n-C12H25)2(CH3)2NBr) at different levels of the cation exchange capacity (CEC), was reported. According to XRPD data, the basal spacing of the smectite phase unit cell increased systematically up to >38(...)

The arrangement of bisphenol A molecules into organoclays and their interactions withthe intercalated surfactant were studied. The organoclays were prepared via solid-state intercalationof four cationic surfactants, such as dodecyltrimethyl-, tetradecyltrimethyl-, hexadecyltrimethyl-,and didodecyldimethyl-ammonium, as bromide salts, at differe(...)

Solid-state intercalation was applied to prepare organo-smectites using cationic surfactants and natural clays containing smectite at various surfactant/smectite ratios. The surfactants enter the interlayers of smectites causing a swelling of the clays. The used clays were collected in Siétougou and Diabari villages located in the eastern part(...)
