Guryaha Alaabta:
1.Waxay la mid tahay inta badan dareerayaasha organic sida ethanol, ether, benzene iyo xayawaanka iyo saliidaha khudradda. Waa dareere aad u fiican oo loogu talagalay nitrate cellulose, polyvinyl chloride, polyvinyl acetate, polystyrene, resin epoxy, caag dabiici ah iyo synthetic, DDT, 2,4-D iyo walxo badan oo dabiici ah. Waxa loo qaabayn karaa xal liidashada hoose si looga hortago xuubka.
2.Chemical Properties: kooxda carbonyl ee molecule iyo atamka hydrogen ee deriska ah waxay qani ku yihiin falcelinta kiimikada, sifooyinka kiimikaad ee la mid ah butanone. Tusaale ahaan, marka ay oksaydhisku sameeyaan walxaha oksijiinta ee xooggan sida chromic acid, waxay soo saartaa acetic acid, isobutyric acid, isovaleric acid, carbon dioxide iyo biyo. Haydaroojiin katalytic wuxuu bixiyaa 4-methyl-2-pentanol. Badeeco dheeri ah ayaa lagu soo saaraa sodium bisulfite. Uumiga leh xeryahooda kale ee kaarboonyl iyadoo ay jirto kicinta aasaasiga ah. Uumiga leh hydrazine si loo sameeyo hydrazone iyo falcelinta uumiga Claisen oo leh ethyl acetate.
3.Stable: Xasilooni
4.Waxyaabaha la mamnuucay:Soxidants xoog leh,wakiilada yaraynta xooggan, saldhigyo xooggan
5. Khatarta polymerisation:Aan ahayn polymerisation
Codsiga Alaabta:
1.Waxyaabahan waxaa loo isticmaali karaa sida dareeraha dhammaan noocyada warshadaha warshadaha, iyo sidoo kale dareeraha wax soo saarka rinji heer sare ah oo loogu talagalay baabuurta, khadadka, cajaladaha cajaladaha, cajaladaha fiidiyowga iyo wixii la mid ah. Waxa kale oo loo isticmaalaa sida wakiilka dhaymada macdanta, wakiilka saliidda ka saara iyo wakiilka midabaynta ee filimka midabka.
2.Waxa kale oo uu leeyahay milmayn heer sare ah ee xeryahooda organometallic. Peroxide ee alaabtani waa bilawga muhiimka ah ee falcelinta polymerisation ee resins polyesterka. Waxa kale oo loo isticmaalaa sida dareere loogu talagalay synthesis organic iyo nuugista atomiga falanqaynta spectrophotometric.
3. Waxaa inta badan loo isticmaalaa sida dareere ah. Waxa intaa dheer in tiro badan oo rinji, strippers rinjiga, noocyo kala duwan oo resins synthetic sida dareere ah, laakiin sidoo kale loo isticmaalo sida xabagta, DDT, 2,4-D, pyrethroids, penicillin, tetracycline, xabagta caag, nuugista atomiga falanqaynta spectrophotometric ee dareere.
4.Waxa kale oo uu leeyahay milmayn heer sare ah ee xeryahooda organometallic. Waxa kale oo loo isticmaalaa sida wakiilka dhaymada macdanta, wakiilka saliidda ka saara iyo wakiilka midabaynta ee filimka midabka. Waxa kale oo jira qaar ka mid ah cusbada inorganic kala soocida wax ku ool ah, laga sooci karaa laga bilaabo plutonium uranium, niobium ka tantalum, zirconium ka hafnium, iwm MIBK peroxide waa hindise muhiim ah in falcelinta polyester resin polymerisation.
5. Loo isticmaalo sidii falanqeeye falanqeyn ah, sida heerarka falanqaynta chromatographic. Sidoo kale loo isticmaalo sida dareerayaasha, wakiilada soo saarista.
6.Isticmaalay soo saarista ciddiyaha ciddiyaha ee alaabta la isku qurxiyo. Ciddiyaha sida dareere-kulanka dhexdhexaadka ah (100 ~ 140 ° C), siinta cidiya polis si ay u faafto, joojiso dareenka qallafsan.
7.Waxa loo isticmaalaa sida dareere loogu talagalay rinjiga buufinta, nitrocellulose, qaar ka mid ah ether fiber, camphor, dufan, caag dabiici ah iyo synthetic.
Qoraalada Kaydinta Alaabta:
1. Ku kaydi bakhaar qabow oo hawo leh.
2. Ka fogow dabka iyo isha kulaylka.
3. Heerkulka kaydinta waa in aanu dhaafin 37°C.
4.Ka ilaali weelka oo xiran.
5. Waa in si gooni ah loo kaydiyaa walxaha oksida,yaraynta wakiilada iyo alkalis,waana inaan marnaba la isku darin.
6.Isticmaal nalalka aan qarxin iyo tas-hiilaadka hawo-siinta.
7. Mamnuuci isticmaalka qalabka farsamada iyo qalabka si fudud loo dhalin karo.
8.Aagga kaydinta waa in lagu qalabeeyaa qalab daawaynta degdega ah ee daadsan iyo agab hoy oo ku habboon.
