Bayanin Acid Dyes
1.Tarihin rini na acid
A cikin 1868, an sami rini na farko na acid, azaman rinayen acid methane acid, wanda ke da ƙarfi.riniiyawa amma rashin saurin gudu.
A cikin 1877, an haɗa rini na farko na acid don rini ulu, kamar yadda ja A. An ƙaddara tsarin asali.
Bayan 1890, an ƙirƙiri rini na acid tare da tsarin anthraquinone.Kuma yana da ƙarin cikakkun bayanai na chromatography.
Ya zuwa yanzu, akwai kusan ɗaruruwan nau'ikan rini na acid, waɗanda aka fi amfani da su a cikin rini na ulu, siliki da nailan, da sauransu.
2.Siffar rini na acid
Ƙungiyar acidic a cikin rini na acid gabaɗaya ta dogara ne akan rukunin sulfonic acid (-SO3H) kuma ya wanzu a cikin nau'in gishirin sodium sulfonic acid (-SO3NA) akan kwayoyin rini.Kuma wasu sun dogara ne akan sodium carboxylate (-COONa).
Rinyoyin Acid suna da kyakkyawan narkewar ruwa, inuwar launi mai haske, cikakken chromatography da mafi sauƙin tsarin kwayoyin halitta fiye da sauran rina.Har ila yau, don rashin tsarin haɗin kai na dogon lokaci a cikin kwayoyin rini, kai tsaye na rini na acid yana da ƙasa.
3.The dauki inji dyes acid
Wool - NH3+ + -O3S - Rini → Wool - NH3+·-O3S - Ruwa
Silk - NH3+ + -O3S - Rini → Siliki - NH3+·-O3S - Ruwa
Nailan - NH3+ + -O3S - Rini → Nailan - NH3+·-O3S - Ruwa
Rabe-raben rini na Acid
1.Classification ta kwayoyin tsarin rini iyaye
∎ Rini na Azo (Asusu na kashi 60% mai faɗi)
Anthraquinone dyes (Asusun don kashi 20% galibi jerin shuɗi ne da kore)
∎ Rini na methane triaromatic (Asusun don 10% Purple da kore jerin)
∎ Rini na heterocyclic (Asusun don 10% jerin ja da shunayya.)
2.Rarraba ta pH na rini
∎ Rini na Acid a cikin ruwan wanka mai ƙarfi na acid: Rini ƙimar pH shine 2.5 ~ 4.Sautin haske yana da kyau, amma saurin sarrafa rigar ba shi da kyau.Launi mai launi yana da haske kuma kayan daidaitawa yana da kyau.
∎ Rini na Acid a cikin raunin acid bath: Rini ƙimar pH shine 4 ~ 5.Adadin ƙungiyar sulfonic acid a cikin tsarin kwayoyin halitta na rini yayi ƙasa.Don haka narkewar ruwa ya ɗan yi rauni.Tsaurin rikon rigar ya fi rini na acid a cikin ruwan wanka mai ƙarfi, ammadaidaitawadukiya ta dan talauce.
∎ Rini na Acid a cikin wankan acid tsaka tsaki: Rinin pH shine 6 ~ 7.Adadin ƙungiyar sulfonic acid a cikin tsarin kwayoyin halitta na rini ya ragu.Solubility na rini yana da ƙasa kuma dukiyar daidaitawa ba ta da kyau.Inuwar launi ba ta da haske sosai, amma saurin sarrafa rigar yana da girma.
