| Nā Code Risk | 36/37/38 – Hoʻonanea i nā maka, ʻōnaehana hanu a me ka ʻili. |
| Ka wehewehe palekana | S26 – Inā pili me nā maka, e holoi koke me ka wai nui a e ʻimi i ka ʻōlelo aʻo kino. S36 – E komo i nā lole pale kūpono. |
Hoʻolauna
ʻO ka 4-Nitro-3,5-dimethylbenzoic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
- 4-Nitro-3,5-dimethylbenzoic acid he paʻa kala kala ʻole me ka ʻono ʻala.
- Paʻa ia ma ka lumi wela, akā hiki ke pahū i nā wela kiʻekiʻe, i ka mālamalama, a i ʻole ke ʻike ʻia i nā kumu hoʻā.
- Aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, ethers, a me nā hydrocarbons chlorinated.
E hoʻohana:
- Hoʻohana nui ʻia ka 4-nitro-3,5-dimethylbenzoic acid ma ke ʻano he waena o nā dyes a me kahi mea maka no ka synthesis o nā puaʻa.
Hanana:
- Hiki ke loaʻa ka 4-Nitro-3,5-dimethylbenzoic acid ma ka nitrification o p-toluene. Hoʻohana maʻamau nā hopena Nitrification i ka hui ʻana o ka waikawa nitric a me ka waikawa sulfuric ma ke ʻano he mea nitrifying.
- ʻO ke ʻano hoʻomākaukau kikoʻī maʻamau: hui ʻia ka toluene me ka waikawa nitric a me ka waikawa sulfuric, hoʻomehana ʻia no ka pane ʻana, a laila crystallized a hoʻomaʻemaʻe ʻia.
ʻIke palekana:
- ʻO ka 4-Nitro-3,5-dimethylbenzoic acid he mea hoʻonāukiuki a ʻino a pono e pale ʻia i ka pili ʻana me ka ʻili a me nā maka.
- I ka lawelawe ʻana i kēia pūhui, e hoʻokomo i nā mīkina lima pale, nā mea hanu, a me nā makaaniani pale e pale aku ai i ka hanu ʻana i nā kinoea a i ʻole ke komo ʻana me ka ʻili.
- I ka mālama ʻana a me ka mālama ʻana, e pale i ka hoʻopili ʻana me nā mea oxidants, nā kumu hoʻāla a me nā mea hiki ke pale aku i ke ahi a pahū paha.
- I ka hihia o ka ʻai ʻana a i ʻole ka inhalation, e ʻimi koke i ka lāʻau lapaʻau a hōʻike i ka pepa ʻikepili palekana huahana i kāu kauka.
