Gabatarwa

Dibromomethane. Mai zuwa shine gabatarwa ga kaddarorin, amfani, hanyoyin shiri da bayanan aminci na dibromomethane:

 

inganci:

Yana da ƙamshi mai ƙamshi a cikin ɗaki kuma ba shi da narkewa a cikin ruwa, amma yana narkewa a yawancin kaushi na halitta gama gari.

Dibromomethyl wani abu ne mai tsayayye na sinadarai wanda baya rubewa ko fuskantar halayen sinadaran cikin sauki.

 

Amfani:

Ana amfani da Dibromomethane sau da yawa azaman ƙaushi don halayen halayen ƙwayoyin halitta, narkar da ko cirewar lipids, resins da sauran abubuwan halitta.

Ana kuma amfani da Dibromomethane azaman albarkatun ƙasa don shirye-shiryen sauran mahadi, kuma yana da aikace-aikace a wasu hanyoyin masana'antu.

 

Hanya:

Dibromomethane yawanci ana shirya shi ta hanyar mayar da methane tare da bromine.

A ƙarƙashin yanayin halayen, bromine zai iya maye gurbin ɗaya ko fiye da hydrogen atom a cikin methane don samar da dibromomethane.

 

Bayanin Tsaro:

Dibromomethane mai guba ne kuma ana iya shanye shi ta hanyar shakar numfashi, tuntuɓar fata, ko sha. Bayyanuwa na dogon lokaci na iya yin illa ga lafiya.

Ya kamata a sa kayan kariya da suka dace kamar safar hannu, tabarau, da garkuwar fuska lokacin amfani da su.

Yakamata a kula don gujewa tuntuɓar hanyoyin kunna wuta lokacin sarrafawa da adana dibromethan, saboda yana da ƙonewa.

Ya kamata a adana Dibromomethane nesa da tushen zafi da yanayin zafi mai zafi a wuri mai sanyi, da isasshen iska.

Lokacin amfani, adanawa ko sarrafa dibromomethane, yakamata a bi amintattun hanyoyin aiki don tabbatar da amincin mutum. Idan akwai haɗari, yakamata a ɗauki matakan gaggawa da suka dace.
