Benzyl Chloride
Chidule cha Zamalonda
Benzyl Chloride (yomwe imadziwikanso kuti Benzyl Chloride, α-Chlorotoluene) ndi mankhwala ofunikira kwambiri achilengedwe okhala ndi formula ya mankhwala C₇H₇Cl ndi kulemera kwa molar kwa 126.58 g/mol. Yodziwika ngati mwala wapangodya mu kapangidwe ka mankhwala abwino, imagwiritsidwa ntchito kwambiri m'mafakitale ophera tizilombo, mankhwala, zonunkhira, utoto, ndi ma polima. Benzyl Chloride yathu imatsatira miyezo yapadziko lonse lapansi, yokhala ndi kapangidwe kokhazikika, magwiridwe antchito odalirika, komanso kuwongolera kwambiri kuipitsidwa - zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri popanga mankhwala apamwamba.
Ndi ukadaulo wapamwamba wopangira chlorination komanso ukadaulo wokonzanso zinthu wopangidwa ndi patent, timaonetsetsa kuti zinthuzo zimakhala bwino nthawi zonse zomwe zimakwaniritsa zosowa zosiyanasiyana za mafakitale. Chogulitsachi chimawoneka ngati madzi opanda mtundu kapena achikasu pang'ono oyera okhala ndi fungo lonunkhira bwino, losakanikirana ndi ethanol, chloroform, ether, ndi zinthu zina zachilengedwe, pomwe sichisungunuka m'madzi (kusungunuka: 460 mg/L) komanso chotha kusungunuka ndi nthunzi ya madzi.

.Mapulogalamu Osiyanasiyana a Mafakitale
Kusinthasintha kwa Benzyl Chloride kumachokera ku kusinthasintha kwake kwabwino, komwe kumagwira ntchito ngati maziko omangira mankhwala ambiri amtengo wapatali:
Makampani Opangira Mankhwala Ophera Tizilombo
Kupanga mwachindunji mankhwala ophera fungicide a organophosphorus monga Kitazin P ndi Iprobenfos, omwe amagwiritsidwa ntchito kwambiri poletsa kuphulika kwa mpunga.
Chofunika kwambiri popanga mankhwala ophera tizilombo (monga phoxim) ndi mankhwala ophera udzu, zomwe zimathandiza kupanga bwino ulimi.
Makampani Opanga Mankhwala
Zinthu zofunika kwambiri popanga maantibayotiki (monga benzylpenicillin), ma antihistamines (monga Diphenhydramine Hydrochloride), ndi ma antiseptics (monga Bromogeramine).
Choyambira cha phenylacetic acid ndi mankhwala ena ochiritsira, zomwe zimathandiza kupanga mankhwala osiyanasiyana ochiritsira.
Makampani Opangira Zonunkhira ndi Utoto
Kupanga mowa wa benzyl, benzyl acetate, ndi zinthu zina zonunkhira zomwe zimagwiritsidwa ntchito mu zonunkhira, zodzoladzola, ndi mankhwala a tsiku ndi tsiku.
Chogwiritsidwa ntchito pakati pa zinthu zothandizira utoto ndi m-phenoxybenzaldehyde, zomwe zimathandiza kuti utoto ukhale wolimba komanso wokhazikika wa nsalu ndi zokutira.
Zowonjezera za Polima ndi Pulasitiki
Kupanga butyl benzyl phthalate (BBP), pulasitiki yogwira ntchito bwino kwambiri yomwe imawonjezera kusinthasintha ndi kulimba kwa ma polima.
Zipangizo zopangira ma resin opangidwa ndi zinthu zoletsa moto, zomwe zimapangitsa kuti zinthu zapulasitiki zisawonongeke komanso kuti zisawonongeke ndi moto.
Mapulogalamu Ena
Kupanga phenylacetonitrile, benzoyl chloride, ndi aniline kuti zigwiritsidwe ntchito bwino.
Amagwiritsidwa ntchito mu zomaliza nsalu, zowonjezera zotsukira, ndi mankhwala opangira ma electroplating, zomwe zimasonyeza kuti mafakitale amatha kusinthasintha mosavuta.
Chitsimikizo cha Ubwino ndi Kutha Kupereka
Ukadaulo Wopanga Zapamwamba: Umagwiritsa ntchito njira zamakono zoperekera chlorine ndi kukonza zinthu kuti zitsimikizire kuti zinthuzo zimakhala bwino komanso kuti pakhale zodetsa zochepa.
Kuwongolera Ubwino Kwambiri: Gulu lililonse limayesedwa mwamphamvu (njira ya GC/FID) kuti litsimikizire kuyera, kuchulukana, ndi kuchuluka kwa zinthu zodetsedwa, ndipo Satifiketi Yowunikira (COA) imaperekedwa pa kutumiza kulikonse.
Kupereka Zinthu Zambiri: Chothandizidwa ndi fakitale yopanga zinthu yapamwamba kwambiri padziko lonse yokhala ndi mphamvu zokwana matani 60,000 pachaka, yokhoza kukwaniritsa zofunikira zopezera zinthu zambiri komanso za nthawi yayitali.
5. Zosankha Zokonzera: Zimapezeka m'mabotolo agalasi a 100 ml, 1 L, 2.5 L, ndi migolo ya PE/chitsulo ya 50 kg, mogwirizana ndi miyezo yapadziko lonse yotumizira ndi kusungiramo zinthu.
Malangizo a Chitetezo ndi Kusamalira
Zambiri Zokhudza Zoopsa (Kutsatira GHS)
Zizindikiro za Ngozi: H302 (Yoopsa ikamezedwa), H315 (Imayambitsa kuyabwa pakhungu), H317 (Ingayambitse ziwengo pakhungu), H318 (Imayambitsa kuwonongeka kwakukulu kwa maso), H331 (Yoopsa ikapezedwa), H335 (Ingayambitse kuyabwa pakhungu), H350 (Ingayambitse khansa), H373 (Ingayambitse kuwonongeka kwa ziwalo chifukwa chogwiritsa ntchito nthawi yayitali).
Mawu Okhudza Chiwopsezo: R22, R23, R37/38, R41, R45, R48/22.
Njira Zopewera
Valani magolovesi oteteza, zovala zosagwira mankhwala, zoteteza maso, ndi zophimba nkhope mukamagwira.
Pewani kukhudzana mwachindunji ndi khungu, maso, ndi njira yopumira; tsukani bwino ndi madzi kwa mphindi 15+ ngati zakhudzana.
Sungani m'nyumba yosungiramo zinthu yozizira, youma, komanso yodutsa mpweya wabwino (kutentha ≤30°C, chinyezi ≤70%) kutali ndi zinthu zoyatsira moto, zotenthetsera mpweya, ndi ufa wachitsulo.
Onetsetsani kuti mpweya wabwino ukulowa bwino mukamagwiritsa ntchito; gwiritsani ntchito mu chivundikiro cha utsi pa ntchito zazing'ono.
Tayani zinyalala ndi madzi otayira motsatira malamulo a zachilengedwe am'deralo kuti muchepetse kuwonongeka kwa chilengedwe.
Mawu Oteteza
S45: Funani upangiri wa dokotala nthawi yomweyo ngati mwachita ngozi kapena kusasangalala (onetsani chizindikiro cha mankhwala ngati n'kotheka).
S53: Pewani kuwonetsedwa - funsani malangizo apadera musanagwiritse ntchito.
Lumikizanani nafe kuti mupeze mayankho osinthidwa
Kuti mudziwe mitengo, zitsanzo, kapena zikalata zonse za TDS/COA, funsani gulu lathu logulitsa:
