FLUOROALKYL PHOSPHATES, METHOD FOR THEIR PREPARING AND ELECTROLYTES BASED ON THEREOF Russian patent published in 2005 - IPC

FIELD: organic chemistry, chemical technology, electrolytes.

SUBSTANCE: invention relates to new fluoroalkyl phosphates that can be used as electrolytes in primary current sources, secondary current sources, capacitors, super capacitors and/or galvanic units. Invention describes fluoroalkyl phosphates of the general formula (I): Mⁿ⁺[PF_x(C_yF_2y+1-zH_z)_6-x]_n wherein 1 ≤ x ≤ 6, 1 ≤ y ≤ 8, 0 ≤ z ≤ 2y + 1, 1 ≤ n ≤ 5 and Mⁿ⁺ means a monovalent, bivalent or trivalent cation, in particular: NR¹R²R³R⁴, PR¹R²R³R⁴, P(NR¹R²)_kR³ _mR⁴ _4-k-m (wherein k = 1-4; m = 0-3 and k + m ≤ 4), C(NR¹R²)(NR³R⁴)(NR⁵R⁶), C(aryl)₃, Rb or tropylium wherein R¹-R⁸ mean hydrogen atom (H), alkyl or (C₁-C₈)-aryl that can be substituted partially for F, Cl or Br atoms and wherein Mⁿ⁺ means Li⁺, Na⁺, Cs⁺, K⁺ and Ag⁺ are excluded. Except for, invention describes a method for preparing fluoroalkyl phosphates and electrolytes for primary current sources based on fluoroalkyl phosphates. Invention provides preparing new compounds possessing useful properties.

EFFECT: improved preparing method, valuable properties of compounds.
