Hoʻolauna
ʻO C6H8O4S ka papa hana kemika, i kapa pinepine ʻia ʻo TDGA. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
ʻO ka Thiodiglycolic anhydride he wai ʻeleʻele a ʻulaʻula me ka ʻala ʻala. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik he nui, e like me nā waiʻona, ethers a me nā esters.
E hoʻohana:
Hoʻohana pinepine ʻia ʻo Thiodiglycolic anhydride ma ke ʻano he reagent kemika, ka mea nui no ka synthesis o nā kemika a me nā solvents. Hoʻohana nui ʻia ia i loko o nā kīhāpai, plastic a me ka pena, a hoʻohana pinepine ʻia i ka hoʻomākaukau ʻana i nā catalysts, antioxidants a me nā plasticizers.
Hanana:
Hiki ke hoʻomākaukau ʻia ka Thiodiglycolic anhydride e ka hopena o ka sodium sulfur chloride (NaSCl), acetic anhydride (CH3CO2H) a me trimethylamine (N(CH3)3). ʻO nā pane kikoʻī penei:
NaSCl CH3CO2H N(CH3)3 → C6H8O4S NaCl (CH3)3N-HCl
ʻIke palekana:
ʻO ka Thiodiglycolic anhydride he mea hoʻonāukiuki a hiki ke hoʻoulu i ka mumū o nā maka a me ka ʻili i nā kiʻekiʻe kiʻekiʻe. Pono e mālama ʻia nā hana palekana i ka wā e hoʻohana ai, e like me ke komo ʻana i nā mīkina lima, nā maka aniani a me nā lole pale. I ka manawa like, e hōʻoia i ka hoʻohana ʻia ʻana ma kahi wahi e hoʻoheheʻe maikaʻi ʻia a pale i ka hoʻohu ʻana i kona mahu. Inā pili, holoi me ka wai nui a ʻimi koke i ka lāʻau lapaʻau. I ka wā o ka mālama ʻana, pono e mālama ʻia ka Thiodiglycolic anhydride i loko o kahi pahu i hoʻopaʻa ʻia, ma kahi mamao o ke ahi a me nā mea hoʻonā.
