Description

Najdluzszy czas trwania patentu do 15 listopada 1943 r.Wedlug patentu glównego bezbarwne produkty stopienia otrzymuje sie z kwa¬ sów dwu-alkylo-barbiturowych oraz dwu- metylo-amino-fenylo-dwu-metylo-pyrazolo- nu w ten sposób, ze podczas stapiania skladników oraz podczas oziebiania stopu usuwa sie tlen powietrza zapomoca gazów obojetnych. Jak okazalo sie, mozna zasto¬ sowac tez powyzszy sposób wogóle do produktów stapiania dwu-metylo^amino- fenylo-dwu-metylo-pyrazolonu z innemi zwiazkami, przytem jest rzecza obojetna w jakim stosunku zachodzi stopienie.Przyklad L Mieszanke kwasu fenylo- etylo-barbiturowego i dwu-metylo-amino- fenylo^dwu-metylo-pyrazolonu stapia sie w stosunku czasteczkowym 1 : 1 w pradzie dwutlenku wegla. Stop ochladza sie, prze¬ puszczajac nad nim w dalszym ciagu stru¬ mien dwutlenku wegla, przyczem otrzy¬ muje sie bialy produkt, topiacy sie miedzy 130^133°C.Przyklad II. Postepuje sie jak to wy¬ mieniono w przykladzie I, przyczem uzy¬ wa sie do reakcji dwie czasteczki dwu-ine- tylo-amino-fenylo-dwu-metylo - pyrazolonu.Oziebiony produkt topi sie w granicach 100—129° i rozpuszcza sie tak samo, jak otrzymany w pierwszym przykladzie w al¬ koholu, metanolu oraz acetonie.Przyklad III. W taki sani sposób otrzy¬ many produkt stopienia, powstaly z dwu- /%mctylo-amino-fcnylo-dwu-mctylonpyrazola- nu i uretanu trój-chloro-etylo-alkoholu, w stosunku 1:1, topi sie w 73—75a i rozpu¬ szcza sie w alkoholu, metanolu, estrze oc¬ towym oraz acetonie.Przyklad IV. Wymienione w przykla¬ dzie III skladniki stapia sie ze soba w stosunku 1 : 2, usuwajac jednoczesnie po¬ wietrze; otrzymuje sie przytem bialy pro¬ dukt stopienia, tak samo rozpuszczajacy sie w wyzej wzmiankowanych odczynni¬ kach.Przyklad V. W ten sam sposób poste¬ puje sie przy uzyciu bramo-dwu-etylo-ace- tylo-karbamidu i dwu-metylo-amino-feny- lo-dwu-metylo-pyrazolanu. Produkt reak¬ cji, zawierajacy powyzsze skladniki w sto¬ sunku 1:1, topi sie w granicach 82—86°.Rozpuszcza sie on w wyzej wzmiankowa¬ nych rozpuszczalnikach organicznych tak sarno, jak produkt stopienia w stosun¬ ku 1 :2. PLThe longest term of the patent until November 15, 1943. According to the main patent, colorless fusing products are obtained from di-alkyl-barbituric acids and dimethyl-amino-phenyl-dimethyl-pyrazolone in such a way that during melting the components and during the cooling of the alloy the oxygen in the air is removed by means of inert gases. As it turned out, the above method can also be applied in general to the products of fusing dimethyl-aminophenyl-dimethyl-pyrazolone with other compounds, and it is indifferent to the ratio in which the melting occurs. Example L Mixtures of phenyl-ethyl-acid barbituric acid and dimethylaminophenyl- dimethyl pyrazolone are melted in a molecular ratio of 1: 1 in a carbon dioxide current. The alloy cools as it continues to pass a stream of carbon dioxide over it, yielding a white product, melting between 130-133 ° C. Example II. The procedure described in Example 1 is followed, whereby two molecules of diethyl-amino-phenyl-dimethyl-pyrazolone are used for the reaction. The coated product melts within 100 ° -129 ° and dissolves in this way. the same as that obtained in the first example in alcohol, methanol and acetone. Example III. The melt thus obtained, formed from di- /% m-methylamino-thenyl-di-methylpyrazolane and tri-chloro-ethyl-alcohol urethane, in a ratio of 1: 1, melts at 73-75a and dissolves in alcohol, methanol, acetic ester and acetone. Example IV. The ingredients mentioned in Example III are melted with each other in a ratio of 1: 2, simultaneously removing the air; thus a white melt product is obtained, which is also soluble in the above-mentioned reagents. Example 5 The same is done for the bromo-diethyl-acetyl-carbamide and dimethyl-amino -phenyl-dimethyl-pyrazolate. The reaction product, containing the above components in a ratio of 1: 1, melts in the range of 82-86 °. It is soluble in the above-mentioned organic solvents as much as a molten product in a ratio of 1: 2. PL
