asi-3-yn-2-one (CAS# 1423-60-5) sumo
3-butyne-2-imwe. Iyi inotevera sumo kune hunhu hwayo, chinangwa, nzira yekugadzira, uye ruzivo rwekuchengetedza:
nature:
-Kuonekwa: 3-Butyn-2-imwe imvura isina ruvara kune yakapenya yero.
-Kunhuhwirira: Kunonhuwirira zvakafanana nedoro uye muchero.
-Solubility: inonyungudika mune yakawanda organic solvents senge doro uye ethers.
Chinangwa:
-3-butyne-2-imwe inoshandiswa zvakanyanya mumunda we organic synthesis. Inogona kushandiswa seyakagadzirwa, catalyst, uye solvent yemakemikari maitiro, uye inogona kutora chikamu mune akasiyana organic synthesis maitiro, senge nucleophilic substitution reactions uye coupling reactions.
Kugadzira nzira:
-Imwe nzira yekugadzirira 3-butyne-2-imwe ndeyekuita kweacetone nepropargyl doro. Chekutanga, acetone inobatwa neyakawandisa sodium hydroxide kuti iwane sodium acetate, iyo inozoitwa nepropargyl doro muunganidzi weokisijeni kugadzira 3-butyne-2-imwe.
-Kune dzimwe nzira dzakasiyana dzekugadzira 3-butyne-2-imwe, sekuparadzanisa uye kuchenesa zvine chekuita nezvigadzirwa zvechisikigo, uchishandisa makemikari synthesis nzira, nezvimwe.
Chekuchengetedza ruzivo:
-3-Butyn-2-imwe inogumbura maziso, ganda, uye kufema system, uye inofanira kugezwa pakarepo nemvura pakubata.
-Dzivisa kusangana nemaoxidants akasimba, maasidhi akasimba, uye mabhesi akasimba kudzivirira maitiro ane njodzi.
-Paunenge uchishandisa 3-butyne-2-imwe, magirovhosi ekudzivirira kemikari, magirazi, uye maski anodzivirira anofanira kupfekwa kuti ave nechokwadi chemamiriro ekufema.
Aya ndiwo masimo makuru nezve zvivakwa, mashandisiro, nzira dzekugadzirira, uye ruzivo rwekuchengetedza kwe3-butyne-2-one. Paunenge uchishandisa uye kubata iyi koniyuta, ndapota ita shuwa yekutevera kuchengetedzwa kwemaitiro uye tarisa kune akakodzera ruzivo rwekuchengetedza uye Blue Book reChemical Substances.
