# Improved Process for the Continuous Acylation of 1,3-Benzodioxole

## TL;DR

A new continuous process for acylating 1,3-benzodioxole using a reusable catalyst achieves high conversion and selectivity.

## Contribution

A continuous acylation process with a recyclable catalyst for 1,3-benzodioxole is introduced.

## Key findings

- 73% conversion rate and 62% selectivity achieved in 30 minutes at 100°C.
- The catalyst showed excellent stability and selectivity over a 6-hour continuous run.
- Unreacted 1,3-benzodioxole can be easily separated and recycled via distillation.

## Abstract

The acylation of 1,3-benzodioxole was studied in a continuous process using a recyclable heterogeneous substoichiometric catalyst. In a short time period (30 min), at 100 °C, the conversion rate was 73%, with a selectivity of 62% of the desired acylated product; the reaction was run continuously for 6 h, showing excellent stability and selectivity. Moreover, the unreacted starting material, 1,3-benzodioxole, can be easily separated by distillation and recycled.
