benutzt werden, die Milchsäureester vorzügliche Lösungsmittel sind. So lösen sich beispielsweise Kolophonium, Schellack. Kopale und ähnliche Harze leicht auf und man kann so in gleicher Weise auch Lacke bereiten, welche ausser den Zellulosederivaten noch diese Harze oder letztere allein enthalten.
Das Verfahren ist deshalb von besonderem Wert, weil es mit seiner Hilfe gelingt, die Lacklösungen mit grosser Billigkeit herzustellen ; denn erstens sind die Milchsäureester an und für sich billig und zweitens it man in der Lage, von aromatischen Kohlenwasserstoffen beträchtliche Mengen mitzuverwenden, wodurch sich der Preis noch ermässigt.
Die Verwendungsmöglichkeit so grosser Mengen an aromatischen Kohlenwasserstoffen ist. deshalb besonders wichtig, weil dieselben sehr billig ssind, um so mehr, als man diese Kohlenwasserstoffe nicht in reinem Zustande zuzusetzen bracucht, sondern man auch Mischungen der verschiedenen Homologen verwenden kann, wie die in der Teerdestillat. ion abfallen.

the lactic acid esters are excellent solvents. For example, rosin and shellac dissolve. Copals and similar resins can be easily prepared and varnishes can be prepared in the same way which, in addition to the cellulose derivatives, also contain these resins or the latter alone.
The process is of particular value because with its help it is possible to produce the lacquer solutions with great cheapness; for, firstly, the lactic acid esters are in and of themselves cheap and, secondly, it is possible to use considerable amounts of aromatic hydrocarbons, which further reduces the price.
The possibility of using such large amounts of aromatic hydrocarbons is. It is particularly important because they are very cheap, all the more so since these hydrocarbons do not have to be added in their pure state, but mixtures of the various homologues can also be used, such as those in the tar distillate. ion fall off.
