5-nitroisophthalic acid
ʻIke kumu:
Introduction: 5-nitroisophthalic acid he mea koʻikoʻi ko waena no nā mea hoʻohālikelike non-ionic e like me ka iodohexyl alcohol, iodoparol, iodoformol, etc. ʻO ia hoʻi ka mea hoʻomaka no ka disperse dyes 2, 6-dicyano-4-nitroaniline. ākea o nā noi a me nā manaʻo mākeke.

He mea koʻikoʻi koʻikoʻi no ka disperse dyes. ʻO ia hoʻi ka mea waena o ka lāʻau diagnostic new ubiquitin (X-ray contrast agent); Hoʻohana pū ʻia e synthesize i kahi pūhui lāʻau hou e pili ana i ka PDE IV inhibitor glycolinic acid; Hoʻohana ʻia ʻo ia ma ke ʻano he mea waena no ka disperse dyes (blue azo dyes).
Hoʻohui ʻia ka waikawa sulfuric concentrated (104.3mL, 1.92mol) i loko o ʻekolu mau hue, a laila hoʻohui ʻia ka waikawa isophthalic (40g, 0.24mol), hoʻoulu ʻia a wela i 60 ℃, paʻa no 0.5h, a me 60% nitric acid (37.8g, 0.36). mol) i hoʻohui ʻia no ka hoʻomalu ʻana i ka degere holo wikiwiki. Hoʻohui i loko o 2 mau hola. Ma hope o ka hoʻohui, mālama ʻia ka wela ma 60 ℃ no 2 mau hola. Hoʻolili i lalo o 50 ° C, a laila hoʻohui i 100mL o ka wai. Hoʻomaʻalili ʻia ka mea i ka lumi wela, ninini ʻia i loko o ka kānana, hoʻomoʻi ʻia e wehe i ka waiʻona, holoi ʻia ka keke kānana me ka wai, hoʻokahe ʻia e recrystallize, a ʻo ka huahana keʻokeʻo he 34.6 grams, ʻo ka hua he 68.4%.
25kg/ 3-i-1 pepa-plastic composite eke, a i ole i ulana eke, a i ole 25kg/ pahu pahu (φ410×480mm); Packaging e like me nā koi o ka mea kūʻai aku;
E kūʻai i loko o kahi pahu paʻa i ka ea ma kahi maloʻo a maloʻo maikaʻi ma kahi mamao mai ke ahi a me nā mea puhi.
