Description
Verfahren zur Darstellung eines harzartigen Körpers. Es ist bekannt, dass sich ein harzartiger Körper durch Veresterung des Kondensations- produktes von technischem Kresol und For inaldehyd mit Toluolsulfoclilorid erhalten lässt. Es hat sich gezeigt, dass man diesen harz artigen Körper in seiner Harznatur wesent lich verbessern kann,
wenn nian ihn im Vakuum auf Temperaturen bis auf über 100 C erhitzt.
plan erhält dann einen Körper, der sich vollkommen wie ein Naturharz verhillt. er ist hart, durchsichtig und weist einen höheren ",chnielzpunkt als der Ausgangsstoff' auf.
Man kann das Harz entweder in eiüein Lösungsmittel wie Benzol oder einem Ho mologen auflösen und den liückstand nach Abdestillation des Lösungsmittels erhitzen oder man kann das Harz auch direkt er- lntzen. <I>Beispiel 1:</I> Ein dur;
li Veresterung des Kondensa- tionsproduktes aus technischem Kresol und Formaldeli#,-d mit Toluolsulfoclilorid erhal tenes Harz wird in Benzol aufgelöst, das Lösungsmittel abdestilliert und der Rück- stand nunmehr ini Vakuum bis auf etwa 11U" erwärmt. Man erhält dann ein hartes durehsielitiges Harz.
Beispiel 1I Ein durch V eresterung des Kondensa tionsproduktes von teclinischern Kresöl- und Fornialdehvd mit Toluolsulfoehloric1 in Ben- zollösung erhaltenes Harz wird durch Destil lation ini Vakuum vom Lösungsmittel Be freit und alsdann im Vakuum weiter bis auf etwa 1111" erwärmt.
Method of making a resinous body. It is known that a resin-like body can be obtained by esterifying the condensation product of technical-grade cresol and formaldehyde with toluenesulfocliloride. It has been shown that this resinous body can be significantly improved in its resinous nature,
if it is heated to temperatures of over 100 ° C. in a vacuum.
plan then has a body that hides completely like a natural resin. it is hard, transparent and has a higher "melting point" than the starting material.
The resin can either be dissolved in a solvent such as benzene or a homologue and the residue can be heated after the solvent has been distilled off, or the resin can also be minted directly. <I> Example 1: </I> A major;
The esterification of the condensation product of technical cresol and formaldelium, the resin obtained with toluenesulfocliloride is dissolved in benzene, the solvent is distilled off and the residue is now heated in a vacuum to about 11U. A hard, thermoset resin is then obtained .
EXAMPLE 11 A resin obtained by esterification of the condensation product of technical crescent and formaldehyde with toluene sulphonyl chloride in benzene solution is freed of solvent by distillation in vacuo and then heated further in vacuo to about 1111 ".
