Compounds are identified that act as crystallization suppressants when added to clear brine fluids, significantly lowering the true crystallization temperatures of the brines, and allowing for higher salt content in clear brine fluids. The crystallization suppressants of the invention also allow for the preparation of higher density zinc free brines. Crystallization suppressant blends are also identified that allow for the preparation of high density clear brine fluids with lower viscosities.

Crystallization suppressant combinations for high density clear brine fluids

The crystallization suppressants of the invention also allow for the preparation of higher density zinc free brines.

High densitiy clear brine fluids

Trialkyl metal compounds, such as trialkyl gallium and indium compounds, are prepared in high yield and high purity by the addition of a trialkyl aluminum compound to a mixture prepared by adding a metal trihalide, e.g., GaClor InCl, and a halide salt of a monovalent metal to an ionic liquid such as a molten salt of the formula M[AlRX] wherein M is a monovalent metal such as Li, Na, K or Cs, R is an alkyl group X is a halide and n is a number from 1 to 3, typically at temperatures of from 75 to 160&#xb0; C.

Preparation of tri-alkyl gallium or tri-alkyl indium compounds

A method for inhibiting the premature polymerization and the polymer growth of ethylenically unsaturated monomers is disclosed wherein the method comprises adding to said monomers an effective amount of at least one hydrogen donor or electron acceptor. In a preferred embodiment, the hydrogen donor or electron acceptor is used in combination with a stable nitroxyl free radical.
