An electrolyte includes at least one lithium salt, at least one first organic solvent having a dielectric constant of >90 at 40° C., at least one second organic solvent having a boiling point of <110° C., and at least one phosphite having the formula (I) Ris selected from an n-propoxy group, an iso-propoxy group, a tert-butoxy group, an n-pentafluoropropoxy group, an n-trifluoropropoxy group, an iso-hexafluoropropoxy group, or a tert-nonafluorobutoxy group. R, R, R, and Rare each selected, independently of one another, from H, a trifluoromethyl group, or a C-C-alkyl group which is substituted with a trifluoromethyl group.

Electrolyte comprising a phosphite as an additive or co-solvent, lithium rechargeable battery comprising said electrolyte, and method for producing the phosphite

The present subject matter provides a safe alternative for producing an important intermediate useful for preparing the herbicide glufosinate, without need for chlorine components in the manufacturing process. In particular, a process for preparing alkyl phosphinic aid alkyl ester is provided, including the step of alkylating alkyl phosphinic acid ester in a non-polar solvent in the same apparatus as used to first produce the alkyl phosphinic acid ester, and without isolating the alkyl phosphinic acid ester before the alkylation step is conducted. More specifically, a process is presented for preparing methyl phosphinic acid butyl ester, by alkylating butyl phosphinic acid ester in a non-polar solvent, in the same apparatus as used previously to first produce the butyl phosphinic acid ester and without isolating the butylphosphinic acid ester before alkylation.
