METHOD FOR PRODUCTION OF ALKALI METAL DIALKYLAMIDES |
摘要 |
The present invention relates to a method for producing dialkylamides of the alkali metals by reacting the corresponding dialkylamine with the corresponding alkali metal in the presence of an electron donor substance of the group 1,3-butadiene, isoprene, naphthalene and/or styrene with the formation of low quantities of butenyl dialkylamine. According to said method, the corresponding alkali metal is introduced and suspended in a solvent and the dialkylamine and the electron donor substance are added, such that the dialkylamine is present in an amount up to 45 wt. %, preferably up to 25 wt. %, in particular up to 15 wt. % and the butadiene is present in an amount up to 5 wt. %, preferably up to 3 wt. %, in particular up to 1.5 wt. %. |
