Kiimikada kiimikada-methylene chloride chloride ee laga sameeyay Shiinaha

Hordhaca Waxsoosaarka

Kiimikada hodanka ah waa xirfad-yaqaan xirfad-yaqaanno Shiinaha oo ah darajada warshadaha ee Dichloromethane ee laga sameeyay Shiinaha, oo ku hawlan kiimikooyinka dabiiciga ah muddo 10 sano ah. Bixinta muunad bilaash ah, si diiran ayaan kuugu soo dhaweynaynaa inaad ku iibsato tayo sare oo ah Cas Maya. Kiimikooyinka leh daahir sare iyo qiimo jaban oo naga hooseysa.

Miisaanka Moleculal: 84.93
Guryaha jireed iyo kiimikada: dareeraha jilicsan ee muuqaalka ah, oo la mid ah urta ether iyo macaan.
Cufnaanta qaraabada: D4201.326kg / l.

Bartamitida Dichloromethane iyo Biyo Hydrolysis Finjirowga, Dichloromethane waxaa ku jira xasillooni ganacsi, si looga hortago hydrolysis. Dichlorisomethane iyo feejignaanta sare ee oksijiintu waxay soo saari doontaa isku dhafka qarxa, laakiin aan guban karin, waxaa badanaa loo isticmaalaa warshadaha sunta rasaasta, xalka aan guban iyo dhibic ka jaban.

Ujeeddo
Loogu talagalay soltvent-ka aan la darin: nadiifinta birta, rinjiga rinjiga, wakiilka nabaad-guurka, sedex keligood lafdhabarta. Filim, aerosol, antibiyootigyo iyo fiitamiinno ku jira soosaarka dareeraha; Wakiilka foosha xumaa ee loogu talagalay soo saarista balaastigga injineerinka; waxyaabaha dib u eegista dib-u-dhigga; Waxaa loo isticmaalaa in lagu beddelo adeegsiga F11 iyo F12 ee loogu talagalay isku-darka alaabada; waxyaabaha kiimikada kiimikada ah ee wanaagsan.

Baakadaha, kaydinta iyo gaadiidka
Birta saliida leh, durbaanka birta madow ama haanta xirmooyinka weelka buuxinta weelka ee dichlorisomethane, 80%, waxay bixin karaan difaac nitrogen ah oo loogu talagalay dadka isticmaala faafitaanka. Kaydinta waa in lagu keydiyaa meel qabow oo qalalan, bakhaarradu waa in lagu hayaa si looga fogaado in lala xiriiro uruurinta sare ee oksijiinta ama si looga fogaado taabashada biyaha si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis si aad uga hortagto hydrolysis. Gaadiidka ayaa u hoggaansami doona qodobbada Jamhuuriyadda Dadweynaha ee Shiinaha ee ku saabsan gaadiidka kiimikada halista ah ee wadooyinka waaweyn iyo jidadka tareenka.

Caafimaadka iyo Nabdoonaanta

Sichoromethane xadka qaraxa hawada: 8.1 ~ 17.2%, waxaa iska leh kiimikooyin guban kara. U fiirsashada sare, soo-gaadhista mudada dheer waxay si fudud u keentaa dawakh, hurdo la'aan, lallabo, tinnitus ama kabuubyo addim ah, u dhaqaaq hawada, astaamaha si dhakhso leh ayaa loo soo celiyaa, ma horseedi doonaan waxyeelo waarta. Kala firidhda indhaha sababa xanuun iyo xanaaq, xidhiidh waqti dheer oo maqaarka ah waxay sababi kartaa maqaarka.
