3-CHLORO-2,4-PENTANEDIONE Chemical Properties,Uses,Production
Chemical Properties
clear yellow to very deep brown liquid
Uses
3-Chloro-2,4-pentanedione was used in the synthesis of tetrathiafulvenyl-acetylacetonate (TTFSacacH), precursor of novel redox-active ligands.
General Description
The tautomeric properties of 3-chloro-2,4-pentanedione were studied using gas electron diffraction (GED) and quantum chemical calculations.
Synthesis
123-54-6
1694-29-7
The general procedure for the synthesis of 3-chloro-2,4-pentanedione from acetylacetone under solvent-free conditions was as follows: first, a temperature control device was installed to maintain the reaction temperature at 15°C and the system pressure was adjusted to 1-2 atm. Acetylacetone was introduced continuously into the reaction system via a metering pump at a flow rate of 1 mol/h and chlorine at a flow rate of 1.0 mol/h. The reaction time was strictly controlled to 20 seconds. During the reaction, the temperature at the reactor outlet was gradually increased to 35 °C and the temperature at the outlet of Pipeline 2 was increased to 25 °C. The reaction lasted for 1 h and was terminated and sampled for gas phase analysis. The results showed that the reaction selectivity was 83.1% and the quantitative yield was 79.2%.
