Claims
- 1. A monocarbonate transesterification process comprising reacting, in the presence of a base;
- (A) a beta-fluoroaliphatic carbonate which is saturated, unsaturated, linear or branched compound of the formula, ##STR14## where R.sub.c is selected from the class of a group of the formula, ##STR15## an alkyl radical, a cycloalkyl, aryl radical and combinations thereof which can be carbo-monocyclic, carbo-polycyclic or fused carbo-polycyclic and can have two or more cyclic systems which are connected to each other by a single or double valence bonds or bi- or multi-valent radicals, with
- (B) a compound selected from the class consisting of
- (1) monohydroxy aliphatic alcohols of the formula,
- R.sup.1 OH
- where R.sup.1 represents an aliphatic radical or cycloaliphatic radical having a single --OH radical attached directly to the aliphatic or cycloaliphatic carbon atom where the alcohol can be a primary, secondary or tertiary alcohol including carbo-monocyclic, carbo-polycyclic or fused carbo-polycyclic alcohol systems which are connected to each other by single or double valence bonds or bi- or multi-valent radicals;
- (2) monohydroxy phenol
- R.sub.b OH
- wherein R.sub.b represents an aryl radical having a single --OH radical attached directly to an aryl ring carbon atom wherein the aryl radical can be carbo-monocyclic, carbo-polycyclic, or fused carbo-polycyclic, and can have two or more cyclic systems which are connected to each other by single or double valence bonds or bi- or multi-valent radicals; and
- (3) an ortho-positioned dihydroxy aromatic compound of the formula,
- R.sub.c (OH).sub.n
- wherein R.sub.c represents an aromatic radical having at least two --OH radicals ortho-positioned relative to each other, each hydroxy group being directly attached to adjacent aromatic ring carbon atoms, n being a number at least equal to 2 wherein the R.sub.c radical can be carbo-monocyclic, carbo-polycyclic, and can have two or more cyclic systems connected to each other by single or double valence bonds, or bi- or multi-valent radicals.
- 2. The process of claim 1 wherein the alcohol is of the formula R'OH and R' is an alkyl radical.
- 3. The process of claim 1 wherein the alcohol is of the formula R'OH and R' is an aryl radical.
- 4. A monocarbonate transesterification process comprising contacting in the presence of a base, a bis(beta-fluoroaliphatic) carbonate selected from the class consisting of the formulas ##STR16## a monohydroxy-substituted aliphatic or aromatic compound of the formula
- R.sub.b (OH)
- where R.sub.b is selected from the class consisting of alkyl, cycloalkyl and aryl radicals.
- 5. The process of claim 4 wherein R.sub.b is an C.sub.6-10 aryl radical.
- 6. The process of claim 4 wherein R.sub.b is a C.sub.1-10 alkyl or C.sub.6-10 cycloalkyl radical.
- 7. The process of claim 4 further comprising a solvent.
- 8. The process of claim 7 wherein the solvent is a non-, low-, or medium-polar solvent.
- 9. The process of claim 8 further comprising separating and recovering a resulting non-fluorinated monocarbonate transesterification reaction product.
- 10. The process of claim 5 wherein the monocarbonate transesterification reaction product is diphenyl carbonate.
