BASIL [Biphasic Acid Scavenging utilizing Ionic Liquids] A range of catalytic processes for synthetic organic chemistry. These processes use ionic liquids as solvents, from which it is easy to recover the catalysts. Developed by BASF from 2002 and first commercialized in 2004 for the synthesis of alkoxyphenyl phosphines. Awarded the Entec Medal for safety and environmental innovation in 2005. 

In 2002 BASF established the first dedicated industrial-scale ionic liquid-based process [7]. The so-called BASIL process (BASIL = Biphasic Acid Scavenging utilizing Ionic Liquids) is used for the synthesis of alkoxyphenylphosphines, which are important raw materials in the production of BASF s Lucirines (Scheme 9-3), substances that are used as photoinitiators to cure coatings and printing inks by exposure to UV light. 

In March 2003, the use was reported of ionic liquids in a commercial process by BASF. The reaction of phenylchlorophosphines and ethanol forms alkoxyphenylphosphines 109 along with HCl, which is scavenged by A-methylimidazole (Scheme 48). The [hmim][Cl] salt 110 formed is an ionic liquid with a melting point of 75°C this leads to a biphasic mixture, which can be more easily stirred than a solution containing a suspension. This ionic liquid also acts as catalyst for this process of biphasic acid scavenging utilizing ionic liquids...
