Okhazikika pakupanga mowa wa propargyl, 1,4 butynediol ndi 3-chloropropyne

Dongosolo ladzidzidzi la mowa wa propargyl

Konzani dongosolo loyankhira mwadzidzidzi molingana ndi mikhalidwe ina ya mowa wa propargyl:

I. Makhalidwe a mowa wa propargyl: nthunzi yake ndi mpweya wake ukhoza kupanga chisakanizo chophulika, chomwe chingayambitse kuyaka ndi kuphulika ngati moto wotseguka ndi kutentha kwakukulu.Imatha kuchitapo kanthu ndi okosijeni.Kutentha kumatulutsa mpweya woipa.Zitani ndi okosijeni ndi phosphorous pentoxide.Ndiosavuta kudzipangira ma polymerize ndipo mawonekedwe a polymerization amakula ndi kuchuluka kwa kutentha.Nthunzi yake ndi yolemera kuposa mpweya, ndipo imatha kufalikira patali kwambiri pamalo otsika.Idzayaka moto ndi kuyaka ngati gwero lamoto.Pakakhala kutentha kwakukulu, kupanikizika kwa mkati mwa chombocho kudzawonjezeka, ndipo pali chiopsezo chosweka ndi kuphulika.

II.Mankhwala oletsedwa: oxidants amphamvu, asidi amphamvu, maziko amphamvu, acyl chlorides ndi anhydrides.3, Njira yozimitsira moto: Ozimitsa moto ayenera kuvala masks a mpweya wa fyuluta (masks a nkhope yonse) kapena zopumira zodzipatula, kuvala moto wathunthu ndi zovala zotetezera mpweya, ndikuzimitsa moto kumbali ya mphepo.Chotsani chidebecho kuchokera pamalo oyaka moto kupita pamalo otseguka momwe mungathere.Thirani madzi kuti zotengera zomwe zili pamoto zizizizira mpaka kuzimitsa moto kutatha.Zotengera zomwe zili pamalo ozimitsa moto ziyenera kuchotsedwa nthawi yomweyo ngati zasintha mtundu kapena kutulutsa mawu kuchokera ku chipangizo chothandizira chitetezo.Chozimitsa: madzi ankhuku, thovu, ufa wouma, mpweya woipa, mchenga.

IV.kusamala posungira ndi mayendedwe: sungani m'nkhokwe yozizirira komanso yolowera mpweya.Khalani kutali ndi moto ndi gwero la kutentha.Kutentha kosungirako sikuyenera kupitirira 30 ℃.Sungani zotengera zosindikizidwa.Idzasungidwa mosiyana ndi ma oxidants, ma acid, alkalis ndi mankhwala odyedwa, ndipo kusungirako kosakanikirana sikuloledwa.Siziyenera kusungidwa mochuluka kapena kwa nthawi yayitali.Zowunikira zotsimikizira kuphulika ndi malo olowera mpweya wabwino ziyenera kulandiridwa.Ndizoletsedwa kugwiritsa ntchito zida zamakina ndi zida zomwe zimakhala zosavuta kutulutsa zopsereza.Malo osungiramo zinthu adzakhala ndi zida zowonongeka zowonongeka ndi zipangizo zoyenera kulandira.Dongosolo loyang'anira "zamagulu asanu" la zinthu zapoizoni kwambiri liyenera kukhazikitsidwa mosamalitsa.

V. Kukhudza khungu: vula zovala zomwe zawonongeka nthawi yomweyo ndikusamba ndi madzi ochuluka otuluka kwa mphindi khumi ndi zisanu.Pitani kuchipatala.

Vi.kukhudzana ndi magalasi: kwezani zikope nthawi yomweyo ndikutsuka bwino ndi madzi ochuluka oyenda kapena saline wamba kwa mphindi 15.Pitani kuchipatala.

VII.Kukoka mpweya: kuchoka pamalowa kupita kumalo okhala ndi mpweya wabwino.Sungani thirakiti la kupuma mosatsekeka.Ngati kupuma kuli kovuta, perekani mpweya.Ngati kupuma kwasiya, perekani mpweya wochita kupanga nthawi yomweyo.Pitani kuchipatala.8, Kumeza: nadzatsuka ndi madzi ndi kumwa mkaka kapena dzira woyera.Pitani kuchipatala.

IX.Kuteteza dongosolo la kupuma: mukakhala mlengalenga kuposa muyezo, muyenera kuvala chigoba chodzipangira chokhachokha (chigoba chathunthu).Pakapulumutsidwa mwadzidzidzi kapena kuthawa, chopumira mpweya chiyenera kuvalidwa.

X. kuteteza maso: kupuma kwatetezedwa.

Xi.Chitetezo m'manja: valani magolovesi amphira.

XII.Thandizo la kutayikira: Chotsani ogwira ntchito pamalo otayikirapo ndi kupita nawo pamalo otetezeka mwachangu, kuwapatula, kuwaletsa kulowa ndikudula gwero lamoto.Ndikofunikira kuti ogwira ntchito zadzidzidzi azivala zopumira zokhala ndi mpweya wabwino komanso zovala zoteteza poizoni.Dulani gwero la kutayikira momwe mungathere.Pewani kulowa m'malo oletsedwa monga ngalande ndi ngalande zonyansa.Kutuluka pang'ono: kuyamwa ndi mpweya kapena mchenga.Ikhozanso kutsukidwa ndi madzi ambiri, kuchepetsedwa ndi madzi osamba ndikuyika m'madzi otayira.Zinyalalazo zidzatengedwera kumalo apadera otaya zinyalala.
