Steps:
3 3. Catalytic reaction
The catalytic reaction was carried out after loading 1 g of catalyst into a conventional stainless steel fixed bed reactor (inner diameter 5 mm, length 300 mm). Next, the 75%water-receiving LA was vaporized in the pre-heating line and mixed with N2 beforeintroduction into the reactor via the liquid pump. The product was recovered from thereactor through a heating line into a sample vessel maintained at 5 ° C, at which thecrude droplet and unreacted LA were separated into a crystalline phase and a liquid phase, respectively.
