The material of Mg/Al hydrotalcite (Mg/Al-HT-ATBH) intercalated with 3,4,5-trihydroxybenzoic acid(THBA) had been successfully synthesized by coprecipitation using a T-type microchannel reactor. Thesynthesized hybrids were characterized by XRD and FT-IR. The result showed that intercalation of THBAinto Mg/Al-HT-THBA reached optimum condition at medium acidity equal to pH 8 with molar ratio ofMg2+:Al3+: THBA was 2:1:0,5. Characterization using FT-IR and XRD showed that THBA was intercalated in the interlayer of Mg/Al-HT-THBA replacing NO3-ions. The value of basal spacing d003 shifted from 11.27° to 6.74° and therefore the interlayer distance increased from 7.84 to 13.10 Å.
