Abstract
yynález sa týká N-alkyl-N,N'-dimetyl-1,2-etándiatnínov všeobecného vzorca kde R značí alkylový reťazec s počtom atómov uhlika 8 až 14 a spósobu přípravy týchto zlúčenín,. ktorý spočívá v reakcii N,N'-dimetyl-1,2-etándiamínu s 1-brómalkánom v prostředísuchého benzénu alebo toluénu pri teplote varu rozpúšťadla. Finálně produkty slúžia ako východiskové látky přej oijganickú syntézu, pre přípravu biologicky účinných zlúčenín s povrchovoaktívnymi vlastnosťami.The present invention relates to N-alkyl-N, N'-dimethyl-1,2-ethanediamines formula wherein R is an alkyl chain number carbon 14 to 14 and a process for the preparation of these compounds. which consists in the reaction of N, N'-dimethyl-1,2-ethanediamine with 1-bromoalkane in dry benzene or toluene at the boiling point of the solvent. Finally, the products serve as starting materials for organic synthesis, for biological preparation active compounds with surfactant properties.
Description
Vynález sa týká N-aIkyl-N,N'-dimetyl-l,2-etándiamínov všeobecného vzorcaThe invention relates to N-alkyl-N, N'-dimethyl-1,2-ethanediamines of the general formula
R—M- CH2~ CH2-NH—CHj CHj kde R značí lineámy alkylový reťazec s počtom atómov uhlíka 8 až 14.R-N- CH 2 -CH 2 -NH-C H C H wherein R is a linear alkyl chain having a carbon number 8 to 14.
Pri príprave niektorých derivátov 1,2-etándiamínu, ktoré majú biologické, detergenčné a povrchovoaktívne vlastnosti je výhodné vychádzať z trisubstituovaného diaminu vyššie uvedeného vzorca, pretože je možné na dusík viazať rózne substituenty ovplyvňujúce vyššie uvedené vlastnosti, pričom sa získajú nesymetricky substituované terciárně aminy, ktorých příprava iným spósobom je obtiažna.In the preparation of certain 1,2-ethanediamine derivatives having biological, detergent and surface-active properties, it is preferable to start from the trisubstituted diamine of the above formula, since it is possible to bind to the nitrogen various substituents affecting the above properties to obtain unsymmetrically substituted tertiary amines. preparing in another way is difficult.
Zlúčeniny, ktoré sú predmetom vynálezu, sú nové v chemickej literatúre doteraz neopísané. Spósob přípravy, ktorý je predmetom vynálezu, vychádza z reakcie N,N'-dimetyl-l,2-etándiamínu s příslušným 1-brómalkánom v prostředí suchého benzénu alebo toluénu pri teplote varu rozpúšťadla.The compounds of the invention are novel in the chemical literature not yet described. The process of the invention is based on the reaction of N, N'-dimethyl-1,2-ethanediamine with the appropriate 1-bromoalkane in dry benzene or toluene at the boiling point of the solvent.
V príkladoch je uvedená metóda přípravy vybraných zlúčenín, ktoré sú predmetom vynálezu a ich charakterizácia. Příklady v žiadnom případe neobmedzujú rozsah použitia tejto metody.The examples show a method for preparing selected compounds of the invention and their characterization. The examples in no way limit the scope of use of this method.
