Influence of reactive conditions in the preparation of organoclay from bentonite-prolabo(France) and dimethyldioctadecylammonium chloride (DMDOA) on the distance of the organoclay layers (d₀₀₁) and the level of intrusion into DMDOA bentonite has been studied. Experimental results show that the preparation conditions suitable organic clay from bentonite (France) and DMDOA: volume ratio DMDOA /bentonite: 1.0, temperature 60^oC, reactive time    5 h, the pH of the solution: 9.0; temperature and dry time: 80^oC in 24 h. In this condition, the organoclay products obtained with d₀₀₁ = 39.031Å and organic content of the organoclay is 35.11%. The synthesized samples were characterized using TG- DTA, XRD.
