Hoʻolauna

ʻO ALPHA-Damascone he mea hoʻohuihui mea ola me ke ʻano kemika C11H18O a me ke kaumaha molekala o 166.26g/mol. He wai kala ʻole me ka ʻala ikaika.

 

Hiki ke hoʻohana ʻia ka mea hoʻohui i ka ʻala, ka ʻala a me ka ʻoihana lāʻau. Hoʻohana nui ʻia ia i nā mea ʻala, nā kopa, nā huahana mālama ʻili, nā meaʻai a me nā hoʻomākaukau lāʻau e hoʻonui ai i kona ʻala.

 

Nui nā ala e hoʻomākaukau ai i kēia pūhui, ʻo kekahi o ia ʻano hana maʻamau ma ka hana ʻana i ka 2-butene-1, 4-diol me benzoyl chloride e hoʻohua i ka ALPHA-Damascone.

 

E pili ana i ka ʻike palekana o kēia pūhui, pono e hoʻomaopopo ʻia kēia mau mea:

-He mea hoʻonāukiuki ka hui a hiki ke hōʻeha i ka maka, ka ʻili a me ka ʻōnaehana hanu. I ka wā o ka hoʻohana ʻana, pono e mālama ʻia e pale aku i ka pili ʻana me ka ʻili, nā maka a me ka ʻōpū hanu, a pono e hāʻawi ʻia i ka pale pilikino kūpono.

-Inā hoʻokomo ʻia ka mea hoʻohui a inhaled paha, pono ʻoe e ʻimi koke i ka lāʻau lapaʻau a hana me ia e like me ke kūlana kikoʻī.

-Ma ke kaʻina o ka hoʻohana ʻana, e hoʻolohe i ke ahi a me ka pahū-hōʻike ʻana, mālama ʻia a me ka mālama ʻana i ka wela wela, ka lapalapa a me ke kumu ahi.

-I ka lawelawe ʻana i ka pūhui, e hoʻokō i nā kānāwai olakino a palekana a hōʻoia i nā kūlana ea.
