Das Patent 177615, Klasse 12, betrifft ein allgemein anwendbares Verfahren zur Darstellung von Alkoxyglycolen. The alkoxyglycols have one by the method of patent 177614, Class 12 "Obtained technical usability, which was previously unknown.

Gegenüber dem Verfahren des Hauptpatents bietet diese Umänderung häufig den Vorteil, billigere und leichter zugängliche Ausgangsmaterialien benutzen zu können. Ebenso wie man in dem Verfahren des Hauptpatents von dem Alkoxyacetonitril ausgehend entweder das Alkoxyketon R1-CO-C H2O X darstellen und mit R-HIg kondensieren kann oder umgekehrt R-CO-CH2(OX) mit R1 HIg, so kann man auch hier die Reihenfolge der Reaktionen nach Bedarf abändern und anstatt das Keton R1-C O R aus dem Nitril R1-C N und R-HIg darzustellen, dieses Nitril. R1-CN zunächst mit HIg - C H1(OX) kondensieren und das so erhaltene Keton R1 -C O -C H2(OX) erst in zweiter Linie mit R · HIg kombinieren. Hierbei. kann man das Nitril R1-CN auch durch das Amid R1 -C O · NH2 ersetzen, ebenso wie man auch an Stelle des Alkoxyacetonitrils das Glycoläthyläthersäureamid CH2(OC2HJ-CO-NH2 verwenden kann. Zur Bewerkstelligung der Kondensation kann man sich an Stelle des Magnesiums auch des Zinks oder eines Metallpaares, z. B. des Zinkkupferpaares, bedienen. Compared to the process of the main patent, this change often offers the advantage of being able to use cheaper and more easily accessible starting materials. Just as in the process of the main patent, starting from the alkoxyacetonitrile, either the alkoxyketone R 1 -CO-C H 2 OX can be represented and condensed with R-HIg or, conversely, R-CO-CH 2 (OX) with R 1 HIg can the order of the reactions can also be changed here as required and instead of the ketone R 1 -COR being represented from the nitrile R 1 -CN and R-HIg , this nitrile. R 1 -CN first condense with HIg - CH 1 (OX) and the ketone R 1 --CO --CH 2 (OX) thus obtained is only combined with R · HIg in the second place. Here. the nitrile R 1 -CN can also be replaced by the amide R 1 -CO · NH 2 , just as the glycolethyl ether acid amide CH 2 (OC 2 HJ-CO-NH 2 can also be used in place of the alkoxyacetonitrile zinc or a metal pair, e.g. the zinc-copper pair, can be used instead of magnesium.
Gleiche Moleküle Keton und Chlormethyläthyläther Cl - C H2(O C2 H6) werden in trocknem Äther gelöst und diese Mischung mit angeätztem trocknen Zink versetzt. Man kann die Reaktion, wenn nötig, durch Zusatz eines Metallpaares anregen, muß aberThe same molecules of ketone and chloromethyl ethyl ether Cl - CH 2 (O C 2 H 6 ) are dissolved in dry ether and this mixture is mixed with partially dry zinc. You can, if necessary, stimulate the reaction by adding a metal pair, but you have to
