PRODUCT INTRODUCTION

Description

Tetrabutylammonium hydrogen sulfate is an ammonium salt. It can be used as a solvent for dissolving the ruthenium(II) complex fac-[Ru(CO)2(H2O)3(C(O)C2H5)][CF3SO3]. It can be used as a cocatalyst in the reaction medium for the preparation of alternating polyketones and propionic acid.
