| Nā Code Risk | R22 – Poino ke aleia R26 – He mea ʻawaʻawa loa ma ka inhalation R37/38 – E hoʻonāukiuki i ka ʻōnaehana hanu a me ka ʻili. R41 - Ka pilikia o ka pōʻino nui i nā maka R36/37/38 – Hoʻonanea i ka maka, ka ʻōpū hanu a me ka ʻili. R36/37 – E hoʻonāukiuki i nā maka a me ka ʻōnaehana hanu. |
| Ka wehewehe palekana | S26 – Inā pili me nā maka, e holoi koke me ka wai nui a e ʻimi i ka ʻōlelo aʻo kino. S28 – Ma hope o ka pili ʻana me ka ʻili, holoi koke me ka nui o ke kopa. S36/37/39 – E hoʻohana i nā lole pale kūpono, nā mīkina lima a me ka pale maka/maka. S45 – Inā loaʻa ka pōʻino a i ʻole ka maikaʻi ʻole, e ʻimi koke i ka ʻōlelo aʻo kino (e hōʻike i ka lepili inā hiki.) S28A - S36 – E komo i nā lole pale kūpono. |

99-91-2 - Ke ʻano
E wehe i ka ʻikepili i hōʻoia ʻia
wai keʻokeʻo ma ka lumi wela. Ka helu hehee 20 ~ 21 ℃, ka paila paila 237 ℃, pili pili 1. 1922(20 ℃), refractive index 1.555, flash point 90 ℃. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik.
99-91-2 - Ke Kaʻina Hoʻomākaukau
E wehe i ka ʻikepili i hōʻoia ʻia
mai ka condensation o chlorobenzene me acetic anhydride i mua o ka alumini trichloride.
99-91-2 - Hoʻohana
E wehe i ka ʻikepili i hōʻoia ʻia
Hoʻohana ʻia kēia huahana no ka synthesis o Mandelic Acid, fluorescent whitening agent AD a me nā kemika maikaʻi ʻē aʻe.
| Hoʻohana | Hoʻohana ʻia kēia huahana no ka synthesis o Mandelic Acid, fluorescent whitening agent AD a me nā kemika maikaʻi ʻē aʻe. hoʻohana ʻia e like me nā mea maka no nā kukui fluorescent, nā lāʻau lapaʻau a me nā mea waena |
| hana hana | mai ka hopena o ka chlorobenzene a me ka acetic anhydride: ka anhydrous aluminum chloride, anhydrous carbon disulfide a me ka maloʻo chlorobenzene hoʻomehana pū, ma hope o ka hoʻoulu ʻana, ua hoʻokuʻu mālie ʻia ka anhydride acetic i loko o ka hui i ka manawa o ka paila iki. Ma hope o ka hoʻohui, ua hoʻoulu ʻia ka hui ʻana a refluxed no 1H e hoʻihoʻi hou i ka carbon disulfide. Ke hooluolu ka reactant i ka lumi wela a mehana, e ninini malie i loko o ka hau pa'i i loa'a ka waika hydrochloric ma lalo o ka ho'ouluulu ana, a e akaka ka stratification. Inā ʻaʻole maopopo, pono e hoʻohui ʻia kahi wahi liʻiliʻi o ka waika hydrochloric. Ma hope o ka ninini ʻana i kahi benzene liʻiliʻi i loko o kēia hopena, ua unuhi ʻia ka ʻaila ʻaila, a lawe hou ʻia ka papa wai me benzene. Ua hui pū ʻia ka extract me ka ʻaila ʻaila, holoi ʻia me kahi 15% sodium hydroxide e wehe i ka acidity, a laila holoi ʻia me ka wai a hiki i ke kū ʻole a maloʻo, ma hope o ka distillation ma lalo o ke kaomi hoʻemi, ua hōʻiliʻili ʻia nā ʻāpana crude a maloʻo no 48h. Ua hoʻokaʻawale ʻia ka waiʻona makuahine a ua hoʻoheheʻe ʻia nā kristal i mea i hoʻopau ʻia. ʻO 83.1% ka hopena. |
