Gabatarwa
Diphenylamine wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga kaddarorin, amfani, hanyoyin shiri da bayanan aminci na diphenylamine:
inganci:
Bayyanar: Diphenylamine wani farin lu'ulu'u ne mai ƙarfi tare da ƙamshin amine mai rauni.
Solubility: Yana da narkewa a cikin kaushi na halitta kamar ethanol, benzene da methylene chloride a dakin da zafin jiki, amma maras narkewa a cikin ruwa.
Kwanciyar hankali: Diphenylamine yana da ɗan kwanciyar hankali a ƙarƙashin yanayi na al'ada, zai oxidize a cikin iska, kuma yana iya haifar da iskar gas mai guba.
Amfani:
Dye da pigment masana'antu: Diphenylamine ne yadu amfani a cikin kira na dyes da pigments, wanda za a iya amfani da su rina zaruruwa, fata da kuma robobi, da dai sauransu.
Binciken sinadarai: Diphenylamine shine muhimmin reagent a cikin haɗin gwiwar kwayoyin halitta kuma galibi ana amfani dashi don gina haɗin carbon-carbon da carbon-nitrogen bond.
Hanya:
Hanyar shiri na gama gari na diphenylamine ana samun su ta hanyar amsawar amino dehydrogenation na aniline. Yawancin lokaci ana amfani da masu kara kuzarin gas-phase ko palladium catalysts don sauƙaƙe abin da ya faru.
Bayanin Tsaro:
Numfashi, sha, ko hulɗa da fata na iya haifar da haushi kuma yana lalata idanu.
Lokacin amfani da ɗauka, ya kamata a guji hulɗa da fata da idanu, kuma ya kamata a la'akari da yanayin samun iska mai kyau.
Diphenylamine ne mai yuwuwar cutar sankara kuma yakamata a bi hanyoyin aiki na aminci da ya dace kuma a bi ƙa'idodi sosai. Ya kamata a sa kayan kariya da suka dace lokacin amfani da aiki da su a cikin dakin gwaje-gwaje.
Abin da ke sama taƙaitaccen gabatarwa ne ga kaddarorin, amfani, hanyoyin shirye-shirye da bayanan aminci na diphenylamine. Don ƙarin cikakkun bayanai, da fatan za a tuntuɓi wallafe-wallafen da suka dace ko tuntuɓi ƙwararru.
