✦ Synopsis

Direct measurements using a variable pressure low temperature liquid cell and infrared spectroscopy have shown that CH3OH, C2H5OH and H2S are considerably less soluble in liquid nitrogen and liquid oxygen, i.e. < 10 -7 mole fraction at 135 K, compared with previously reported values of 10 -5 mole fraction for CH3OH and C2H5OH in liquid oxygen at 77 K and 10 -7 mole fraction for H2S in liquid nitrogen at 77 K using a gravimetric method. Some criteria for assessing and measuring the solubility of compounds in cryogenic liquids are proposed.

## Abstract __The effect of the incorporation of either ester or ester and ether functions into the side chain of an 1‐alkyl‐3‐methylimidazolium cation on the physico‐chemical properties of ionic liquids containing bis(trifluoromethylsulfonyl)imide or octylsulfate anions is studied. It is believed
