Antibacterial ionic liquids with 1-alkyl-1-methyl-4-piperidinolium cation and (S)-mandelate anion, method for obtaining them and the application as antibacterial agents

摘要

Antibacterial ion fluids with 1 -alkyl -1 -methyl -4 -piperidine cation and (S)-almond anion of general formula 1 are the subject of the notification,in which R stands for an alkyl base of two to 16 carbon atoms. The notification shall also include the means of receipt,which is based on this,that 1 -alkyl -1 -methyl -4 -piperidine oil bromide of a general formula 2,in which R stands for an alkyl base of two to 16 carbon atoms,is dissolved in methanol,or ethanol,or 1 -propanol,or 2 -propanol,followed by the addition of lithium or potassium salt or sodium (S)-almolic acid in molar ratio from 1 to 1,1,the system is then mixed in temperature from 15 to 40oC,favourable 20oC,between twenty minutes and one hour,favourable thirty minutes,then the extracted inorganic salt is removed,and then evaporate the solvent from the transfer,and the rest dry. The notification shall also cover the use of ion fluids as antibacterial agents.
