Thioglycolic acid CAS No. 34590-94-8

Sharaxaad Gaaban:

Thioglycollic acid (TGA) ayaa inta badan loo isticmaalaa sida walxo ceeriin ah oo loogu talagalay wakiilka bustaha dhammeeya iyo xalka feeraha qabow. TGA waxay leedahay sifooyinka falcelinta ee labada hydroxyl acid iyo kooxda sulfhydryl, falcelinta ugu muhiimsan waa falcelinta disulfide. Gaar ahaan, waxay la falgashaa cystineka timaha ee xaaladaha alkaline, waxay gooysaa (-SS-) bond of cystine, waxayna abuurtaa cysteine ​​Chemicalbook acid taas oo sahlan in la duubo. Inta badan loo isticmaalo sida wakiilka curling, wakiilka timaha ka saarida, polyvinyl chloride sun hooseeyo ama aan sun ahayn xasiliye, polymerization initiator, dardariyaha iyo wakiilka wareejinta silsilad, wakiilka daawaynta dusha biraha. Intaa waxaa dheer, thioglycolic acid waa reagent xasaasi ah oo loogu talagalay go'aaminta birta, molybdenum, aluminium, tiin, iwm. Waxa kale oo loo isticmaali karaa sida wakiilka nucleating crystallization ee farsamaynta polypropylene iyo qaabaynta, iyo sidoo kale beddelka daboolka, fiilooyinka, iyo wakiilka degdegga ah ee bustayaal.

Codsiga

Inta badan loo isticmaalo sida wakiilka curling, wakiilka timaha ka saarida, polyvinyl chloride sun hooseeyo ama aan sun ahayn xasiliye, polymerization initiator, dardariyaha iyo wakiilka wareejinta silsilad, wakiilka daawaynta dusha biraha.

Dipropylene glycol methyl ether waa dareere dabiici ah oo leh noocyo kala duwan oo warshado iyo adeegsi ganacsi ah. Waxay u aragtaa isticmaalka bedel yar oo aan xasilloonayn oo loo beddelo propylene glycol methyl ether iyo ethers glycol kale. Badeecada ganacsigu caadi ahaan waa isku dhafka afar isomers.

Loo isticmaalo dareere ahaan nitrocellulose, ethyl cellulose, polyvinyl acetate, iwm.; sida dareere loogu talagalay nitrocellulose, ethyl cellulose, polyvinyl acetate, iwm, sida dareeraha rinjiga iyo rinjiga, iyo sida qayb dareere ah Loo isticmaalo sida dareere daabacaadda khad iyo dhaldhalaalka, iyo sidoo kale dareere ahaan loo isticmaalo dhaqidda saliidda goynta iyo saliidda shaqada. Loo isticmaalo sida isku-xidhka rinjiga rinjiga biyaha ku salaysan (badanaa isku dhafan);

Walxaha firfircoon ee rinjiga biyaha ku salaysan;

Wakiilka dareeraha iyo isku xidhka ee nadiifinta guriga iyo warshadaha, dufanka iyo rinjiga ka saara, nadiifinta birta, nadiifinta dusha adag;

Walxaha aasaasiga ah iyo wakiilada isku xidhka ee khadadka daabacaadda shaashadda ku salaysan dareeraha;

Wakiilka isku-xidhka iyo dareeraha ee dharka dheeha dheeha;

Wakiilka isku dhafka ah iyo wakiilka daryeelka maqaarka ee qaababka qurxinta; xasiliyaha sunta cayayaanka beeraha; xinjirowga lidka ku ah ee dhulka iftiimiya.

Goobaha Codsiga

Dahaarka: Xalka wanaagsan ee xabagta oo ay ku jiraan acrylics, epoxies, alkyds, resins nitrocellulose iyo resins polyurethane. Cadaadiska uumiga oo aad u hooseeya iyo heerka uumi-baxa oo gaabis ah, biyo-xumo dhammaystiran iyo sifooyin isku dhafan oo wanaagsan.

Wakiilka nadiifinta: kacsanaan hoose oo hoose, ur caraf udgoon oo hooseeya iyo heerka uumiga oo hooseeya. Solubility wanaagsan ee walxaha polar iyo non-polar labadaba, waa doorasho wanaagsan oo loogu talagalay nadiifinta iyo nadiifinta sagxadda.

Faa'iidada

Tayada badeecada, tiro ku filan, gaarsiinta wax ku oolka ah, tayada sare ee adeega Waxay leedahay faa'iido ka badan amine la mid ah, ethanolamine, in diirada sare loo isticmaali karo isla awooda daxalka. Tani waxay u ogolaanaysaa sifeeyayaasha inay xoqaan hydrogen sulfide oo ah heerka amiinada wareega hoose ee isticmaalka tamarta guud.
