Description

  

  Verfahren zur Darstellung eines stark basischen     Porphins.       Das vorliegende Verfahren betrifft die  Darstellung eines stark basischen     Porphins     und ist dadurch gekennzeichnet,     dass    man       Pyrroporphyrin    mit     Diäthylamiiioäthanol    be  handelt.  



  <I>Beispiel:</I>  <B>1</B>     gi-        Pyrroporphyrin    wird im Heizbad  mit<B>5</B> ein'     Diäthylamiiioäthariol   <B>5-6</B> Stun  den lang auf<B>155 0</B> erhitzt. Es tritt quanti  tative Unisetzung zu einem stark basischen       Porphin    ein. Das Produkt kristallisiert beim       Ei-kalten    in grossen prismatischen Nadeln aus  und wird durch     Umkristallisieren    aus einem  Gemisch von Chloroform und     Diäthylamitio-          äthatiol    mit einem     korr.        Smp.    von<B>1880</B> er  halten.

   Zur Analyse wurde das mehrfach       umkristallisierte    neue     Porphin    im Hoch  vakuum bei<B>25'</B> zur Gewichtskonstanz ge  trocknet.     Ber.    für     C97H4ssO2N5,   <B>C 74,96</B>     0/".          #        7,83%,        N        11,82%,        Gef.        C        74,3601/0,          #        7,84"/o,        N        11,87%.     



  Das neue stark basische     Porphin    stellt  einen dunkelrotbraunen Farbstoff dar, dessen       Basizität    so gross ist,     dass    er einer ätherischen    Lösung mit beliebig schwachen Säuren quan  titativ entnommen werden kann. Die Lösung  seiner Salze mit starken Säuren in Wasser  reagiert neutral und zeigt     Neutralspektrum.     



  Die Analyse bestätigt das Vorliegen eines  von     Pyrroporphyrin    verschiedenen, neuen     Por-          phins.  



  Process for the preparation of a strongly basic porphine. The present method relates to the preparation of a strongly basic porphine and is characterized in that pyrroporphyrin is treated with diethylamiioethanol.



  <I> Example: </I> <B> 1 </B> gi- pyrroporphyrin is in the heating bath with <B> 5 </B> a 'diethylamiiioethariol <B> 5-6 </B> hours on < B> 155 0 </B> heated. Quantitative dissolution to a strongly basic porphine occurs. When the egg is cold, the product crystallizes in large prismatic needles and is recrystallized from a mixture of chloroform and diethylamitioethatiol with a corr. Mpt. Of <B> 1880 </B>.

   For the analysis, the repeatedly recrystallized new porphine was dried to constant weight in a high vacuum at <B> 25 '</B>. Ber. for C97H4ssO2N5, <B> C 74.96 </B> 0 / ". # 7.83%, N 11.82%, found. C 74.3601 / 0, # 7.84" / o, N 11, 87%.



  The new, strongly basic porphine is a dark red-brown dye, the basicity of which is so great that it can be quantitatively taken from an ethereal solution with any weak acids. The solution of its salts with strong acids in water reacts neutrally and shows a neutral spectrum.



  The analysis confirms the presence of a new porphin other than pyrroporphyrin.

The new, strongly basic porphine is a dark red-brown dye, the basicity of which is so great that it can be quantitatively taken from an ethereal solution with any weak acids. Die Lösung seiner Salze mit starken Säuren in Wasser reagiert neutral und zeigt Neutralspektrum. Die Analyse bestätigt das Vorliegen eines von Pyrroporphyrin verschiedenen, neuen Por- phins. Das neue Produkt soll zu färberischen Zwecken Verwendung finden. The solution of its salts with strong acids in water reacts neutrally and shows a neutral spectrum. The analysis confirms the presence of a new porphin other than pyrroporphyrin. The new product is to be used for dyeing purposes.
