ʻO ka waika DSD (4,4 diaminostilbene mono-2,2 bisulfonic acid) he mea koʻikoʻi ia no ka hana ʻana i nā mea hoʻomālamalama fluorescent, pololei melemele G, melemele pololei R, ʻalani pale ʻole o ka lā F3G a me nā mea ʻai anti-moth. ʻO ka COD he 6000-8000mg / L, salinity he 6% -8%, a he 50,000 mau manawa ke kala; ʻO nā mea nui o ka wai ʻōpala he mau mea ʻala ʻala me ka nitro, amino a me nā pūʻulu sulfonic, a ʻo ka ratio o BOD i COD he 0.03 wale nō, he paʻakikī loa ka biodegrade.

ʻO ka maikaʻi o ka wai a me ka nui o ka wai o ka DSD acid production wastewater he paʻa, akā he kiʻekiʻe loa ka chromaticity a me ka sulfate concentration, nele nā ​​​​meaʻai e like me N a me P, a loaʻa i ka wai ʻino nā mea ʻawaʻawa a me nā mea ʻino, ʻaʻohe laʻana lapaʻau kūleʻa. Kina. ʻO ka waika dsd he paʻi melemele māmā a i ʻole ka pauka, hiki ke hoʻoheheʻe ʻia i ka ethanol a me ka etera, hiki ʻole ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka hopena alkali. (2) He mea maʻalahi ka oxidized i ka ʻulaʻula, a loaʻa nā waiwai o nā ʻakika aromatic a me nā amines i ka manawa like.

3) Ka maikaʻi o ka huahana a me ka helu ʻenehana: ka nui o ka amino waiwai (e like me ka nui o ka paʻi) ≥48%; huahana maloʻo huina amino waiwai (e like me ka huina o ka maloʻo laʻana) ≥95.0%; alkali insoluble mea maʻiʻo (e ka huina o ka paʻi) ≤0.05%; alkali insoluble mea maʻiʻo (e ka nui o ka pauda) ≤0.08%; mea benzyl (ma ka huina o nā laʻana) ≤0.25% no ka hana ʻana i ka mea hoʻomaʻemaʻe ʻulaʻula, ka mea hoʻomaʻemaʻe ʻulaʻula, ka mea keʻokeʻo fluorescent, ka mea keʻokeʻo fluorescent, ka mea keʻokeʻo fluorescent. ka mea hoʻomaʻemaʻe, keʻokeʻo keʻokeʻo, ka mea hoʻomaʻemaʻe keʻokeʻo, ka mea hoʻomaʻemaʻe keʻokeʻo, ka mea hoʻomaʻemaʻe keʻokeʻo, ka mea keʻokeʻo keʻokeʻo. E kuhikuhi i ka melemele maloʻo G a me ka melemele pololei R, a hoʻohana ʻia ma ke ʻano he lāʻau lāʻau lāʻau.

ʻO ka hoʻopaʻapaʻa hui ʻana. ʻO ka inoa piha ʻo 4,4`-diaminostilbene-disulfonic acid. Hiki ke hoʻohana ʻia no ka synthesis o ka mea keʻokeʻo fluorescent a me nā mea ʻē aʻe. CAS No.: 81-11-8 Molecular Formula:C14H14N2O6S2 Molecular Weight:370.4008 Quality Index（Specification） Look（Hisona）： light yellow powder/light yellow paste Content（Purity）：≥95. 0 Hoʻopaʻa (Paʻi): 25 mg/kg.

0 Hoʻopaʻa (Package): 25kg/40kg/bag Nā Waiwai Kino Kaona Molecular Weight: 370.4, ʻeleʻele melemele a māmā paha me ka hygroscopicity. He mea maʻalahi ke oxidize i ka ea. He mea ʻawaʻawa kēia huahana a hoʻonāukiuki i ka ʻili, e pale i ka pilina pololei me ke kino kanaka.

ʻO ke ala Synthesis: ʻO ke ʻano hana synthesis o kēia manawa ʻo ka p-nitrotoluene sulfonated me ka fuming sulfuric acid, a laila hoʻoheheʻe ʻia me ka wai, a hoʻokaʻawale ʻia ka NTS i hoʻokaʻawale ʻia ma lalo o nā kūlana alkaline me ka ea, a ʻo ka DNS i loko o ka hopena oxidation e hoʻoheheʻe ʻia me ka paʻakai, a laila hoʻemi ʻia me ka hao. ka pauda, ​​a laila hoʻohāinu ʻia me ka sulfuric acid. Ua maloʻo a maloʻo ka pauka. Kūʻai ʻia ka pauda ma ke ʻano he huahana pulu no nā kūʻai kūloko, akā kūʻai ʻia ma ke ʻano pauda no ke kālepa honua.

ʻO ka hui ʻoihana ʻo Mit-ivy ka mea e hana nui ai i ka DSD ACID me ka mana hana makahiki o 1,000,000 tons, a he 97% ka māhele mākeke.
