Thermal optimisation of the Reimer–Tiemann reaction using thermochromic liquid crystals on a microfluidic reactor
Lab on a chip, 2005Co-Authors: Alexander Iles, Robin Fortt, Andrew J. De MelloAbstract:Microreactors incorporating thin film resistive heating elements for continuous flow organic synthesis are presented. Internal thermal conditions were monitored in real time using reflectance spectra of temperature sensitive thermochromic liquid crystals (TLC) in a collateral microfluidic network. To demonstrate the precise temperature control provided by this method, the thermal optimisation of the Reimer-Tiemann Formylation of beta-naphthol was performed under hydrodynamic pumping regimes.

Synthesis of 4-Hydroxy-2-Methylchalcone from meta-Cresol Formilation Product and Its Activities as an Antibacteria
Jurnal Kimia Sains dan Aplikasi, 2018Co-Authors: Ismiyarto Ismiyarto, Suyanti Suyanti, Ngadiwiyana Ngadiwiyana, Purbowatiningrum Ria Sarjono, Nor Basid Adiwibawa PrasetyaAbstract:Research on the synthesis of 4-hydroxy-2-methylchalcone from 4-hidroksi-2-metilbenzaldehida as formilated meta-cresol product and its antibacterial activity test has been conducted. As the first step, synthesis of 4-hydroxy-2-methylbenzaldehyde was carried out by treatment meta-cresol with chloroform through the Reimer-Tiemann Formylation. Product is a brown solid with 23.94% yields. Furthermore, the 4-hydroxy-2-methylchalcone was synthesized using the 4-hydroxy-2-methylbenzaldehyde and acetophenone through the Claisen-Schmidt reaction. The product is a brownish yellow solid with 29.74% yields. Antibacterial test against Escherichia coli and Staphylococcus aureus bacteria was carried out by comparing the activity of 4-hydroxy-2-methylchalcone with 4-hydroxy-3-methoxychalcone, and chalcone compounds. The antibacterial activity test showed that the 4-hydroxy-2-methylchalcone compound, 4-hydroxy-3-methoxychalcone, and chalcone compounds gave a better antibacterial activity against Escherichia coli than the Staphylococcus aureus.
