Introduction

• An inorganic nonaqueous solvent is a solvent
  other than water, that is not an organic
  compound. examples are liquid ammonia, liquid
  sulfur dioxide, sulfuryl chloride and
  sulfurychloride fluridef, phosphoryl chloride,
  dinitrogen tetroxide, antimony trichloride,
  bromine pentafluoride, hydrogen fluoride, pure
  sulfuric acid and other inorganic acids. These
  solvents are used in chemical research and
  industry for reactions.
