| Nā Code Risk | R36/37/38 – Hoʻonanea i ka maka, ka ʻōpū hanu a me ka ʻili. R26 – He mea ʻawaʻawa loa ma ka inhalation R22 – Poino ke aleia |
| Ka wehewehe palekana | S26 – Inā pili me nā maka, e holoi koke me ka wai nui a e ʻimi i ka ʻōlelo aʻo kino. S37/39 – E hoʻohana i nā mīkina lima kūpono 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.) S36/37 – E hoʻohana i nā lole pale kūpono a me nā mīkina lima. S28 – Ma hope o ka pili ʻana me ka ʻili, holoi koke me ka nui o ke kopa. |

Ke hoʻolauna nei i ka p-Ethoxyacetophenone (CAS # 1676-63-7)
He hui nui a koʻikoʻi i ka honua o ka kemika organik a me nā noi ʻoihana. ʻO kēia ketone aromatic, i hōʻike ʻia e kāna hui ethoxy, he wai kala ʻole a ʻeleʻele melemele me kahi ʻala ʻoluʻolu a ʻono, e lilo ia i mea waiwai i nā ʻano hana like ʻole.
Hoʻohana nui ʻia ka p-Ethoxyacetophenone ma ke ʻano he kikowaena koʻikoʻi i ka synthesis o nā lāʻau lapaʻau, agrochemical, a me nā mea ʻala. ʻO kāna ʻano kemika kūʻokoʻa e hiki ai iā ia ke komo i nā ʻano like ʻole, me ka Friedel-Crafts acylation a me ka nucleophilic substitutions, e hoʻolilo iā ia i poloka hale waiwai no nā chemists a me nā mea hana like. ʻO ke kūpaʻa a me ka hana ʻana o ka pūhui he koho kūpono no ka hana ʻana i nā molekala paʻakikī i nā hoʻonohonoho noiʻi a me ka hoʻomohala ʻana.
I loko o ka ʻoihana ʻala, mahalo ʻia ka p-Ethoxyacetophenone no kona hiki ke hāʻawi i kahi leka momona a me ka pua i nā mea ʻala a me nā huahana mālama pilikino. ʻO kona hiki ke hoʻoheheʻe ʻia i loko o nā solvents like ʻole e hoʻonui i kona versatility, e ʻae ana i nā mea hoʻokumu e hana i kahi ākea ākea o nā kiʻi ʻala e ʻoluʻolu i nā mea kūʻai. Eia kekahi, ʻo kāna volatility haʻahaʻa e hōʻoia i ka mālama ʻana o nā mea ʻala i ko lākou kūpaʻa i ka manawa, e hāʻawi ana i nā manaʻo mau loa.
Eia kekahi, ke loaʻa nei ka p-Ethoxyacetophenone i ka traction ma ke kahua o nā photoinitiators no nā uhi a me nā inika UV-curable. ʻO kona hiki ke komo i ke kukui UV a hoʻomaka i ka polymerization e lilo ia i mea koʻikoʻi i ka hana ʻana i nā hoʻopau lōʻihi a kiʻekiʻe.
Me kāna mau noi like ʻole a me ka ulu ʻana o ka noi, p-Ethoxyacetophenone he mea pono e loaʻa i nā poʻe loea i ka ʻoihana kemika, lāʻau lapaʻau, a me nā ʻoihana hoʻonaninani. Inā ʻoe e ʻimi nei e hoʻomaikaʻi i kāu hoʻomohala huahana a ʻimi paha i nā ala synthetic hou, hāʻawi ka p-Ethoxyacetophenone i ka hilinaʻi a me ka hana āu e pono ai. Hoʻopili i ka hiki o kēia pūhui kupaianaha a hoʻokiʻekiʻe i kāu mau papahana i kahi kiʻekiʻe.
