2,5-Dimethoxybenzaldehyde(CAS No.: 93-02-7) he mea koʻikoʻi koʻikoʻi. Ma muli o kona ʻano kemika kūʻokoʻa a me ka versatility, noho ʻo ia i kahi kūlana koʻikoʻi ma nā kahua o ka lāʻau lapaʻau a me ka ʻoihana kemika. ʻO kona maʻemaʻe kiʻekiʻe a me ka reactivity kona mau pono nui, akā pono e uku ʻia i ka pale palekana i ka wā o ka hana. ʻO ka noiʻi e hiki mai ana e pili ana i ka synthesis ʻōmaʻomaʻo a me ka hoʻohana waiwai e hoʻonui hou i kāna mau hiʻohiʻona noi.

2,5-DimethoxybenzaldehydeCAS 93-02-7He mea koʻikoʻi koʻikoʻi ka mea hoʻohui me nā mea hoʻohana, nā hiʻohiʻona a me nā pono:

1. Noi

(1) Nā kikowaena lāʻau lapaʻau:2,5-Dimethoxybenzaldehydehoʻohana nui ʻia i ka synthesis lāʻau lapaʻau, no ka laʻana, ma ke ʻano he kī waena no ka hoʻomākaukau ʻana i nā mea antibacterial, nā lāʻau antiviral a i ʻole nā ​​molekole organik paʻakikī.
(2) Ka lole a me ka ʻoihana ʻala: Ma ke kahua o nā mea ʻala a me nā mea ʻala, hiki ke hoʻohana ʻia ka 2,5-Dimethoxybenzaldehyde ma ke ʻano he mea maka no ka synthesis o nā mea ʻala, e hāʻawi ana i ka huahana i kahi ʻala a i ʻole kala.
(3) Fungicide a me ka preservative: Ua hōʻike kekahi mau haʻawina e hiki ke hoʻohana ʻia ka 2,5-Dimethoxybenzaldehyde ma ke ʻano he precursor o nā fungicides a i ʻole preservatives, ʻoi loa i ka hoʻomohala ʻana i nā huahana kūlohelohe.
(4) Organic synthesis noiʻi: 2,5-Dimethoxybenzaldehyde hoʻohana pinepine ʻia i ka condensation reactions, redox reactions, etc.

2. Na ano

(1) Ka waiwai kino a me ke kemika
Ka helu hoʻoheheʻe: 46-48°C (lit.), ka pauka crystalline melemele māmā.
Ka helu hoʻolapalapa: 283.8°C ma ke kaomi maʻamau, 146°C ma ke kaomi haʻahaʻa (10 mmHg), kūpono no nā hopena wela kiʻekiʻe14.
Solubility: hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, etera, chloroform, a hiki ke hoʻoheheʻe iki ʻia i ka wai.
Māmā: ma kahi o 1.1 g/cm³, helu kuhikuhi refractive 1.534.

(2) Paʻa a me ka naʻau:
Paʻa i ka ea, pono e hoʻopaʻa ʻia a mālama ʻia mai ka mālamalama e pale ai i ka oxidation a decomposition.
Paʻa nā waiwai kemika, akā hiki ke hoʻololi i ke alo o nā oxidants ikaika.

(3) Nā hiʻohiʻona palekana:
Hazard: He mea hoʻonāukiuki (GHS07/GHS08). Hiki i ka hoʻopili ʻana me ka ʻili a i ʻole nā maka ke hoʻonāukiuki, a me ka inhalation hiki ke hoʻoulu i ka maʻi hanu.
Pono e mālama ʻia i loko o kahi anuanu a maloʻo a pale i ka hoʻopili ʻana me nā oxidants ikaika.

3. Pono

(1) Hoʻoikaika kiʻekiʻe: ʻO ka hopena synergistic o nā pūʻulu aldehyde a me methoxy e hana maikaʻi loa i ka synthesis organik, kūpono loa no ke kūkulu ʻana i nā hale molekala paʻakikī.
(2) ʻano like ʻole:2,5-Dimethoxybenzaldehydehiki ke hoʻohana ʻia ma ke ʻano he kumu hoʻomaka no nā ʻano like ʻole, e like me ka condensation, alkylation, etc., a ʻo kāna ʻano noi e uhi ana i nā kahua he nui e like me ka lāʻau lapaʻau a me nā mea.
(3) ʻO ka ʻoihana ʻoihana makua: ʻO ke kaʻina hana o 2,5-Dimethoxybenzaldehyde he ʻano makua. Hiki iā mākou ke hāʻawi i nā kikoʻī like ʻole (e like me 99% maʻemaʻe) a me ka hoʻopili (25kg / barrel, 500g / ʻeke, a me nā mea ʻē aʻe) e hoʻokō i nā pono ʻoihana a me nā ʻoihana.
(4) Hiki ke palekana kaiapuni: Ua hōʻike ʻia nā haʻawina2,5-Dimethoxybenzaldehydehiki ke hana hou ʻia ma o ka ʻohi ʻana i ka ʻōpala (e like me nā derivatives lignin), e like me ke ʻano o ka ulu ʻana o ke kemika ʻōmaʻomaʻo.
