Ukunyibilika kwamanzi: ukunyibilika, ukunyibilika kwi-methanol kunye ne-ethanol.
Imbonakalo :umgubo omhlophe okanye ulwelo olungenambala
UNhm.: 1431/4.2
Ukuzinza: ubuthathaka emoyeni kunye nokufuma, ngokukhawuleza ukubola kwi-methanol kunye ne-sodium hydroxide emanzini, kwaye ibolile emoyeni ngaphezu kwe-126.6 ℃.
Kukho iintlobo ezimbini zesodium methoxideiimveliso: okuqinileyo kunye nolwelo.Isiqina yimethoxide yesodium ecocekileyo kwaye ulwelo sisinyibiliko semethanol sesodium methoxide.Umxholo we-sodium methoxide yi-27.5 ~ 31%.Ulwelo lwemethoxide yesodium lulwelo olungenambala okanye olutyheli lweviscous, lunobuntununtunu kwioksijini, luyavutha kwaye luyaqhushumba.Ukufunxa ngokulula ukufuma.Ukunyibilika kwi-methanol kunye ne-ethanol, ukubola kwi-methanol kunye ne-sodium hydroxide emanzini, kwaye ibole emoyeni ngaphezu kwe-126.6 ℃.Ayinyibiliki kwi benzene kunye ne toluene.Iyacaphuka kakhulu kwaye iyadleka.Isetyenziswe njenge-ejenti yokunciphisa, i-alkaline catalyst eyomeleleyo kunye ne-agent ye-methoxylating ukulungiselela iikhemikhali ezifana neekhemikhali Incwadi ye-Vitamin B1 kunye ne, i-sulfadiazine kunye nokunye.Isixa esincinci sisetyenziselwa ukuveliswa kwezitshabalalisi.Isenokusetyenziswa njenge-catalyst yokunyangwa kwamafutha atyiwayo kunye neoli etyiwayo, ingakumbi amafutha aqholiweyo.Inokusetyenziswa kwakhona njenge-reagent analytical.I-sodium methoxide eqinile yi-amorphous powder engenambala, evakalelwa kwi-oksijini, enokutsha, i-soluble kwi-methanol kunye ne-ethanol, idibene ne-methanol kunye ne-sodium hydroxide emanzini, kwaye ibolile emoyeni ngaphezu kwe-126.6 ℃.Isetyenziswa kakhulu kwimveliso ye-sulfonamides, i-VB6 kunye ne-va.I-sodium methoxide ikwayi-catalyst ye-organic synthesis, esetyenziswa kwimveliso ye-pesticide kunye ne-oyile processing industry.
2.Usetyenziso oluphambili
1).I-sodium methoxide ineendlela ezininzi zokusetyenziswa, ngokukodwa ezisetyenziselwa ukuveliswa kwe-sulfonamides kunye nokunye.
2).Isetyenziswa njengesiseko se-condensation agent kunye ne-catalyst kwi-organic synthesis, kwaye isetyenziselwa ukuhlanganiswa kweziqholo kunye nedayi.Yimathiriyeli ekrwada ye-vitamin B1, a kunye ne-sulfadiazine.
3).Isetyenziswa njengento ekrwada iyeza kunye nesibulali-zinambuzane.Yinto ebalulekileyo ekrwada yokwenziwa kweziyobisi ezifana ne-sulfaimidine, i-sulfamethoxazole kunye ne-sulfa synergist.
4).Isetyenziswe njenge-catalyst yonyango lwamafutha adliwayo kunye neoli edliwayo (ingakumbi i-lard) ukutshintsha isakhiwo samanqatha ukwenzela ukuba ifanele i-margarine kwaye kufuneka isuswe ekutyeni kokugqibela.
3.Ipakethi yokuThumela ngaphandle:
Ukugcinwa kunye neempawu zokuthutha: Indawo yokugcina impahla ingena umoya kwaye yomile kwiqondo lokushisa eliphantsi;Gcina ngokwahlukileyo kwiiasidi kunye nee-oxidants.
4.Amanyathelo oncedo lokuqala
Ukuthintana nolusu: Khulula iimpahla ezinentsholongwane kwaye uhlambe ngamanzi aqukuqelayo imizuzu eyi-15.Kwimeko yokutsha, funa unyango.
Ukujongana kwamehlo: Phakamisa iinkophe ngokukhawuleza kwaye uhlambe ngamanzi aqukuqelayo okanye ityuwa eqhelekileyo kangangemizuzu eli-15 ubuncinane.Bona ugqirha.
Ukuphefumla: Shiya indawo kwindawo enomoya omtsha.Nika ioksijini xa ukuphefumla kunzima.Xa ukuphefumla kuyeka, yenza ukuphefumla okwenziweyo ngoko nangoko.Bona ugqirha.
Ukungeniswa: Gcoba kwangoko kwaye usele ubisi okanye iqanda elimhlophe.Bona ugqirha.
Iindlela zokucima umlilo: Ugwebu, isanti kunye necarbon dioxide.Akukho manzi.
