Abstract
Popisujú sa dusíkaté deriváty esterov kyseliny akrylovej obecného vzorca, kde R je etyl alebo 2-hydroxyetyl. Neutralizáciou s kyselinou mravčou a octovou Je ich možné previesť na příslušné soli. Zlúčeniny sú vhodné ako surovina k príprave polymérov. O O II II ( CHÍ2=CHCOC1í2 )2 (HOCH2) CCH2OCCH2- CH2N(R)2Nitrogen derivatives of acrylic acid esters of the general formula are described, where R is ethyl or 2-hydroxyethyl. By neutralization with formic and acetic acid they can be converted into the corresponding salts. The compounds are suitable as raw materials for the preparation of polymers.

Description
Přípravu zlúčenín je možné uskutočniť posobením dietylamínu na pentaeritritoltriakrylát v molárnom pomere 1 : 1. Neutralizáciou s kyselinou mravčou alebo octovou je ich možné v případe potřeby previesť na příslušné hydrofilné soli. Priebeh adície a kontrol konečného produktu je možné najpresnejšie určovat stanovením obsahu nenasýtených vázieb akrylátů.The preparation of the compounds can be carried out by deposition of diethylamine on pentaeritritol triacrylate in a 1: 1 molar ratio. The course of addition and control of the final product can be most accurately determined by determining the content of unsaturated bonds of acrylates.
Vynález je ďalej objasněný formou príkladov.The invention is further illustrated by way of examples.

Do banky sa předložilo 40 g 50 %-ného roztoku pentaeritritoltriakrylátu v metylalkohole. Pri 40 °C sa pomaly přidalo z oddelovacieho lievika 14 g 50 %-ného dietanolamínu v metylalkohole a násada sa zahríevala 2 h. Za vákua sa oddestiloval metylalkohol. Připravený amínoakrylát o molekulovej hmotnosti 403,43 má aminové číslo 140,3 mg KOH/g, akrylový ekvivalent 0,4965 mól/100 g a nD 20 = 1,4967. Vodné kompozície je možné připravit zmiešaním 5 g aminoakrylátu s 0,6 g kyseliny mravčej alebo 0,8 g kyseliny octovej a rozpuštěním vo vodě.The flask was charged with 40 g of a 50% solution of pentaeritritol triacrylate in methanol. At 40 ° C, 14 g of 50% diethanolamine in methanol was slowly added from the separatory funnel and the batch was heated for 2 h. Methyl alcohol was distilled off under vacuum. The prepared aminoacrylate having a molecular weight of 403.43 has an amine number of 140.3 mg KOH / g, an acrylic equivalent of 0.4965 mol / 100 gan D 20 = 1.4967. Aqueous compositions can be prepared by mixing 5 g of aminoacrylate with 0.6 g of formic acid or 0.8 g of acetic acid and dissolving in water.
