Description
i DK 167933 B1
Den foreliggende opfindelse angår vanduopløselige disazofarvestoffer, en fremgangsmåde til deres fremstilling og deres anvendelse.
I US patentskrift nr. 2.115.030 beskrives azofarve-5 stoffer, som er arylazo-derivater af det monocycliske malo-nylmalonimid. Arylazo-derivaterne, der ikke er sulfonylerede ved den aromatiske kerne, er egnede til farvning af organiske derivater af cellulose, især tekstiler af celluloseacetat. Andre anvendelser er ikke nævnt.

Der foreligger grundlæggende forskelle mellem arylazo-forbindelserne ifølge det ovennævnte US patentskrift og de 15 vanduopløselige disazoforbindelser ifølge opfindelsen.

De forskellige strukturer af forbindelsesklasserne 20 medfører helt forskellige hovedanvendelsesområder. Forbindelserne ifølge us-patentskriftet anbefales til farvning af tekstiler af celluloseacetat ud fra en vandig dispersion.

Fremstillingen af disazofarvestofferne ifølge opfindelsen med formel (I) sker ved kendte metoder ved kobling 10 af de diazoterede aminer med den nævnte koblingskomponent i vandigt medium, eventuelt i nærværelse af ikke-ionogene, anionaktive eller kationaktive, overfladeaktive stoffer. Eventuelt kan der ved fremstillingsprocessen for farvestofferne også anvendes andre hjælpestoffer, såsom naturlige 15 eller syntetiske harpikser eller harpiksderivater eller lak-, trykfarve- eller kunststof additiver. Koblingsreaktionen kan også helt eller delvis ske i organiske opløsningsmidler.
Disazofarvestofferne ifølge opfindelsen med formel 20 (I) er værdifulde, vanduopløselige farvestoffer og kan efter koblingsreaktionen isoleres på gængs måde. Hyppigt er det hensigtsmæssigt at underkaste de efter koblingsreaktionen fremkomne azofarvestoffer, især hvor der er tale om pigmenter, en efterbehandling til opnåelse af den fulde farve-25 styrke og en særlig gunstig krystalstruktur. F.eks. kan til dette formål de fugtige eller tørrede og formalede disazo-farvestoffer opvarmes nogen tid under tilbagesvaling eller tryk til højere temperaturer i organiske opløsningsmidler, f.eks. pyridin, N-methy 1-2-pyrrol idon, dimethyl formamid, 30 dimethylsulfoxid, alkoholer, chlorbenzen, dichlorbenzen, iseddike, quinolin, glycol, nitrobenzen eller højtkogende aromatiske carbonhydrider. I nogle tilfælde lykkes overføringen i en særlig gunstig krystalstruktur også allerede ved opvarmning med vand, eventuelt under tryk og eventuelt 35 under tilsætning af dispergeringsmidler eller organiske opløsningsmidler, f.eks. af den ovenfor nævnte art.

Genstand for opfindelsen er tillige anvendelsen af de ifølge opfindelsen fremstillede, vanduopløselige disazofarvestoffer med formlen (I) til farvning af naturlige 10 eller syntetiske materialer. Alt efter om disazofarvestof-ferne ifølge opfindelsen ingen alkylkæder indeholder eller indeholder korte alkylkæder, op til ca. C4, eller om de indeholder middellange eller lange alkylkæder, er de f.eks. egnede som pigmenter, dispersionsfarvestoffer eller fedtfar-15 vestoffer. Foretrukket er anvendelsen af disazofarvestoffer ifølge opfindelsen med korte alkylkæder eller uden alkylkæder som pigmenter. De er f.eks. egnet til farvning, hhv. pigmentering, af polystyren, polyolefiner, især polyethylen eller polypropylen, polyacrylforbindelser, polyvinylforbin-20 delser, især polyvinylchlorid eller polyvinylacetat, polyestere, gummi, caseinharpikser og siliconeharpikser. De er desuden egnet til fremstillingen af trykfarver, til tilberedningen af lakfarver og dispersionsudstrygningsfarver, til tryk på sådanne underlag som tekstil fibre eller på andre 25 fladeformede produkter, f.eks. papir.
Pigmenterne ifølge opfindelsen kan også - fortrinsvis i findelt form - anvendes til farvning af kunstsilke ud fra viscose eller celluloseethere, celluloseestere, polyamider, polyurethaner eller polyglycolterephthalater i spindemassen 30 eller til indfarvning af papir.
I de efterfølgende eksempler er "dele" baseret på vægten, og "volumendele" forholder sig til vægtdele som liter til kilogram.

Eksempel 1 34,12 dele 3-amino-4-chlorbenzamid udrøres i 200 dele vand med 60 volumendele 31%'s saltsyre natten over. Derefter afkøles til 5°C og diazoteres med 40 volumendele 5 5N natriumnitritopløsning. Der efteromrøres i 1 time, nitritoverskuddet ødelægges med amidosulfonsyre, og diazoniumsalt-opløsningen klares ved filtrering.
16,81 dele l,5-diazabicyclo[3,3,0]-2,4,6,8-tetron suspenderes i 760 dele vand, opløses ved tilsætning af 40 10 volumendele 4N natriumacetatopløsning, hvorefter opløsningen klares.
I koblingsbeholderen fyldes først den klarede diazo-niumsaltopløsning og 20 volumendele af en 10%1 s vandig opløsning af reaktionsproduktet af 1 mol oleylalkohol og 25 mol 15 ethylenoxid. Til denne blanding drypper eller løber ved 10-15° C opløsningen af koblingskomponenten langsomt. Efter endt kobling opvarmes til 80°C ved tilledning af damp, pigmentet frasuges efter 10 minutters forløb, og det vaskes med vand. Derefter blandes den fugtige pressekage med 500 20 volumendele iseddike og opvarmes i 30 minutter til tilbagesvaling. Efter afkøling frasuges pigmentet, vaskes med iseddike og derefter med vand, tørres og formales. Det fremkomne diazopigment svarer til ovenstående formel (I), hvor D1 og D2 hver især betyder gruppen 5-carbamoyl-2-chlorphenyl.
25 Pigmentet sønderdeles ved 346-350°C og giver ved indarbejdning i en alkyd-melaminharpiks-lak farvninger med fortrinlig dækevne, god lysægthed og upåklagelig overlakeringsægthed.
Eksempel 2 30 57,06 dele 3-amino-4-methoxy-N-(4-carbamoylphenyl)- -benzamid omrøres med 800 volumendele iseddike og 60 volumendele 31%'s saltsyre i 1 time, afkøles til 10°C og diazoteres £ied 40 volumendele 5N natriumnitritopløsning. Efter 45 minutters omrøring ødelægges nitritoverskuddet med amidosulfon-35 syre, og diazoniumsaltopløsningen klares.
Diazoniumsaltopløsningen blandes nu med 20 volumendele ^ a ----- DK 167933 B1 13 af en 10%'s vandig opløsning af reaktionsproduktet af 1 mol oleylalkohol og 25 mol ethylenoxid samt 100 volumendele 4N natriumacetatopløsning. Til den fremkomne blanding får ved 15-20°C en svarende til eksempel 1 fremstillet opløsning af 5 koblingskomponenten lov til langsomt at tildryppe.
Efter endt kobling opvarmes til 95°C ved tilledning af damp, og efter 10 minutter ved denne temperatur frasuges pigmentet og vaskes med vand. Den fugtige pressekage blandes under omrøring med 1000 volumendele iseddike, og den frem-10 komne blanding opvarmes i 10 minutter under tilbagesvaling. Efter afkøling frasuges pigmentet, vaskes med iseddike og derefter med acetone, tørres og formales. Strukturen af det fremkomne pigment svarer til formlen (I), hvor D1 og D2 hver især betyder gruppen 5-[4-(carbamoyl)-phenylaminocar-15 bonyl]-2-methoxyphenyl. Pigmentet har et sønderdelingspunkt på 318-319°C. Det giver ved indarbejdning i polyvinylchlorid eller i en alkyd-melamin-lak røde farvninger med fortrinlig migrations- og opløsningsmiddelægthed.
20 Eksempel 3-38 På en måde, som er analog med eksemplerne 1 og 2, fås under anvendelse af diazokomponenter med formel (la) azopigmenter med formel (I), hvori D1 og D2 betyder den med aminogruppen forbundne arylgruppe i formlen (la). Azopig-25 menterne er desuden karakteriseret ved de i nedenstående tabel angivne farvetoner og sønderdelingspunkter (sdp.).
