Methanol is reacted with branched monoolefins such as isobutylene, or mixtures of hydrocarbons such as mixed C-4's from or in a refinery, in the presence of methanesulfonic acid. A column (10) operation is described wherein methanesulfonic acid (11) and methanol (12) are fed in countercurrent fashion to hydrocarbons (13). Crude product ether is removed as a liquid sidestream (25) above the feed of methanesulfonic acid (11), while hydrocarbons depleted of the reactive branched monoolefins (24) are removed overhead. The methanesulfonic acid suppresses the vapor pressure of methanol relative to product ether.

An improved process for the production of methyl ethers of the type in which methanol is reacted with a branched monoolefin in the presence of a catalytically effective amount of one or more acid catalyst, said improvements comprising carrying out said reaction in one or two steps in the presence of one or more liquid organic compounds having one or more hydroxy substituents which functions as a carrier for the branched monoolefins. The hydroxy compound also inhibits the polymerization of the branched monoolefins.

The present invention is directed to a process of oxidizing organic compounds having allylic or benzylic carbon atoms. The process of this invention comprises reacting an organic compound having one or more allylic or benzylic carbon atoms with an effective amount of an effective oxidizing agent in water at a temperature equal to or greater than about 350. degree. C. and at a pressure equal to or greater than about 175 atmospheres, wherein said agent is selected from the group consisting of elemental sulfur, an oxidized form of elemental sulfur and, an organic or inorganic compound capable of forming elemental sulfur or said oxidized forms in situ under process conditions.

Novel fluorogenic ionophores have been synthesized which selectively bind ions such as potassium and sodium, even in neutral aqueous and alcoholic media and respond to such binding by fluorescence quenching or enhancement. These ionophores are ideal for the selective and direct determination of ions in biological or environmental samples and the like. The ionophores are also suitable for incorporation into fiber optic-based sensors for the continuous in vivo or in vitro monitoring of metal ions in blood or other biological fluids.

Beta pinene is converted to alpha pinene in liquid sulfur dioxide. The process is a regioselective isomerization of organic compounds having a carbon-carbon double bond at a tertiary carbon atom, by sulfur dioxide-induced allylic rearrangement of a hydrogen atom and/or replacement of a proton in the allylic position by a deuteron. The organic compound is contacted with sulfur dioxide at temperatures between about 0. degree. and 70. degree. C. for a time sufficient to effect such isomerization to a more stable isomer; and if deuteration is to take place D. sub. 2 O is provided in the solution.
