Phenylacetylene (CAS # 536-74-3) waxay soo bandhigaysaa
tayada
Phenacetylene waa iskudhis organic ah. Waa kuwan qaar ka mid ah sifooyinka phenylacetylene:
1. Qalabka jirka: Phenacetylene waa dareere aan midab lahayn oo ku kacsan heerkulka qolka.
2. Waxyaabaha kiimikaad: Phenylacetylene waxa ay mari kartaa falcelino badan oo la xidhiidha kaarboon-kaarboon saddexle curaarta ah. Waxay la kulmi kartaa falcelin dheeri ah oo leh halogens, sida falcelin dheeri ah oo koloriin ah si loo sameeyo phenylacetylene dichloride. Phenacetylene waxa kale oo ay mari kartaa falcelin dhimis, iyada oo la falgasha hydrogen marka uu jiro wax kicinaya si loo sameeyo styrene. Phenylacetylene sidoo kale waxay fulin kartaa falcelinta beddelka ee reagents ammonia si ay u soo saarto badeecooyinka beddelka ee u dhigma.
3. Xasilooni: Kaarboon-kaarboon-ku-xidhka saddex-laaban ee phenylacetylene ayaa ka dhigaysa in ay yeelato heerar sare oo aan dhereg lahayn. Waa mid aan degganayn oo u nugul falcelinta polymerization-ka ee kediska ah. Phenacetylene sidoo kale aad bay u gubanaysaa waana in laga fogaadaa in lala xiriiro walxaha oksaydhka ee xoogan iyo ilaha dabka.
Kuwani waa qaar ka mid ah sifooyinka aasaasiga ah ee phenylacetylene, kaas oo leh qiimaha codsiga muhiimka ah ee isku-dhafka organic, sayniska alaabta iyo qaybaha kale.
Macluumaadka Badbaadada
Phenacetylene. Waa kuwan qaar ka mid ah macluumaadka badbaadada ee ku saabsan phenylacetylene:
1. Sunta: Phenylacetylene waxay leedahay sun gaar ah waxayna jidhka bini'aadamka ku geli kartaa neefsashada, taabashada maqaarka, ama qaadashada. Soo-gaadhista muddada-dheer ama xooga-saarista sare waxay saamayn xun ku yeelan kartaa neef-mareenka, habdhiska dareenka, iyo beerka.
2. Qaraxa dabka: Phenylacetylene waa walax guban karta oo awood u leh in ay samayso isku dhafka qarxa iyo ogsijiinta hawada ku jirta. Soo-gaadhista ololka furan, kulaylka sareeyo, ama ilaha dabka ayaa keeni kara dab ama qarax. Xidhiidhka walxaha sida oksaydhiyeyaasha iyo asiidhyada xooggan waa in laga fogaado.
3. Iska ilaali neefsashada: Phenylacetylene waxay leedahay ur xun oo sababi karta dawakhaad, lulo, iyo raaxo la'aan xagga neefsiga ah. Hawo wanaagsan waa in la ilaaliyaa inta lagu jiro hawlgalka waana in si toos ah loo neefsado uumiga phenylacetylene ama gaaska waa in laga fogaadaa.
4. Ilaalinta xidhiidhka: Markaad gacanta ku hayso phenylacetylene, xidho galoofyada ilaalinta, muraayadaha indhaha iyo dharka ilaalinta habboon si aad uga fogaato taabashada maqaarka iyo indhaha.
5. Kaydinta iyo maaraynta: Phenylacetylene waa in lagu kaydiyaa meel qabow oo hawo fiican leh, kana fog meelaha dabka iyo ololka furan. Weelka waa in laga eego xaaladdiisa ka hor inta aan la isticmaalin. Habka wax ka qabashada waa in uu raacaa habab hawlgal oo badbaado leh si looga fogaado dhimbiil iyo kharashyo koronto.
Isticmaalka iyo hababka isku dhafan
Phenacetylene waa iskudhis organic ah. Waxay ka kooban tahay giraanta benzene ee ku xiran kooxda acetylene (EtC≡CH).
Phenacetylene waxay leedahay codsiyo kala duwan oo ballaaran oo ku saabsan isku dhafka dabiiciga ah. Waa kuwan qaar ka mid ah isticmaalka ugu muhiimsan:
Isku-dubarid sunta cayayaanka: phenylacetylene waa dhexdhexaad muhiim u ah isku-dhafka qaar ka mid ah sunta cayayaanka sida caadiga ah loo isticmaalo, sida dichlor.
Codsiyada indhaha: Phenylacetylene waxaa loo isticmaali karaa falcelinta sawir-qaadista, sida diyaarinta agabka sawir-qaadista, agabka difaaca jirka, iyo agabka sawir-qaadista.
Hababka isku dhafan ee phenylacetylene ee shaybaarada iyo warshadaha inta badan waa sida soo socota:
Falcelinta acetylene: iyada oo loo marayo falcelinta arylation iyo falcelinta acetylenylation ee giraanta benzene, giraanta benzene iyo kooxda acetylene ayaa ku xidhan si ay u diyaariyaan phenylacetylene.
Dareen-celinta dib-u-habaynta Enol: Enol ee giraanta benzene waxaa lagu falceliyaa acetylenol, falcelinta dib-u-habaynta waxay dhacdaa inay soo saarto phenylacetylene.
Falcelinta Alkylation: giraanta benzene ayaa la saarayaa
