Usetyenziso oluthile
Isetyenziswa ngokubanzi kwi-organic synthesis kwaye yindawo ephakathi ye-anti-infertility drug radiomiphene.
Indlela yokuvelisa:
1. I-P-chlorobenzoyl chloride yalungiswa ngokusabela kwe-p-chlorobenzoyl chloride kunye ne-anisole, ilandelwa yi-hydrolysis kunye ne-demethylation.
2. Ukusabela kwe-p-chlorobenzoyl chloride kunye nephenol: nyibilikisa i-9.4g (0.1mol) ye-phenol kwi-4ml ye-10% yesisombululo se-sodium hydroxide, yongeza i-14ml (0.110mol) ye-p-chlorobenzoyl chloride dropwise kwi-40 ~ 45 ℃. 30min, kwaye usabele kwiqondo lobushushu elifanayo kwi-1H. Ukuphola kwiqondo lobushushu begumbi, hluza kwaye wome ukufumana i-22.3g yephenyl p-Chlorobenzoate. Isivuno ngama-96%, kwaye indawo yokunyibilika yi-99 ~ 101 ℃.

2. Ukusabela kwe-p-chlorobenzoyl chloride ngephenol: nyibilikisa i-9.4g (0.1mol) ye-phenol kwi-4ml ye-10% yesisombululo se-sodium hydroxide, yongeza i-14ml (0.110mol) ye-p-chlorobenzoyl chloride dropwise kwi-40 ~ 45℃, yongeze ngaphakathi kwe-30min, kwaye uphendule kwiqondo lokushisa elifanayo kwi-1H. Ukuphola kwiqondo lobushushu begumbi, hluza kwaye wome ukufumana i-22.3g yephenyl p-Chlorobenzoate. Isivuno ngama-96%, kwaye indawo yokunyibilika yi-99 ~ 101℃.
Ingozi yempilo:
kubangela ukucaphuka kwesikhumba. Banga ukucaphuka kwamehlo okunzulu. Inokubangela ukucaphuka kwendlela yokuphefumla.
Ukulumkela:
Coca kakuhle emva kotyando.
Nxiba iiglavu ezikhuselayo / iimpahla ezikhuselayo / iiglasi ezikhuselayo / iimaski ezikhuselayo.
Kuphephe ukuphefumla uthuli / umsi / igesi / umsi / umphunga / isitshizi.
Sebenzisa kuphela ngaphandle okanye ngokungena komoya olungileyo.
Impendulo yengozi:
Kwimeko yokungcola kwesikhumba: hlamba ngokucokisekileyo ngamanzi.
Kwimeko yokucaphuka kwesikhumba: funa unyango.
Khulula iimpahla ezosulelekileyo kwaye uzihlambe phambi kokuba uphinde usetyenziswe
Ukuba emehlweni: Hlamba ngononophelo ngamanzi imizuzu embalwa. Ukuba unxibe iilensi zokunxibelelana kwaye unokuzikhupha ngokulula, zikhuphe. Qhubeka nokugungxula.
Ukuba usaziva ukucaphuka kwamehlo: bona ugqirha / ugqirha.
Kwimeko yokuphefumla ngempazamo: tshintshela umntu kwindawo enomoya omtsha kwaye ugcine indawo yokuphefumla ekhululekile.
Ukuba uziva ungonwabanga, fowunela iziko lokukhutshwa kwetyhefu emzimbeni/ugqirha
Ugcino olukhuselekileyo:
Gcina kwindawo engenamoya. Gcina isitya sivaliwe.
Indawo yokugcina kufuneka itshixiwe.
Ukukhupha inkunkuma:
Lahla iziqulatho / izikhongozeli ngokuhambelana nemigaqo yendawo.
Amanyathelo oncedo lokuqala:
Ukuphefumla: ukuba urholile, hambisa isigulana kumoya omtsha.
Ukuthintana nolusu: khulula iimpahla ezingcolileyo kwaye uhlambe ulusu kakuhle ngamanzi anesepha kunye namanzi acwengileyo. Ukuba uziva ungaphilanga, bonana nogqirha.
Ukudibana kwamehlo: ukwahlula iinkophe kwaye uhlanjwe ngamanzi aqukuqelayo okanye i-saline eqhelekileyo. Funa unyango ngokukhawuleza.
Ukuginya: rhabula kwaye ungabangeli ukugabha. Funa unyango ngokukhawuleza.
Ingcebiso yokukhusela umhlanguli: dlulisela isigulane kwindawo ekhuselekileyo. Dibana nogqirha. Bonisa le ncwadana yobugcisa yokhuseleko lweekhemikhali kugqirha kwisiza.
