Zotsatirazi ndizofotokozera za chikhalidwe, kugwiritsa ntchito, kukonzekera ndi chitetezo cha trans-2-penten-1-al; 2-pententa; 2-pententa; gamma-methylcrotonaldehyde;Pent-2-enal;FEMA 3218;T2 pentental; TRANS-2-PENTEN-1-AL;PENTENE-2-AL:

 

Chilengedwe:

- trans-2-penten-1-al;2-Pentanal; 2-pententa; gamma-methylcrotonaldehyde;Pent-2-enal;FEMA 3218;T2 pentental; TRANS-2-PENTEN-1-AL;PENTENE-2-AL ili ndi fungo lamphamvu la prenyl aldehyde.

-Zitha kusungunuka muzinthu zambiri zosungunulira organic, monga ma alcohols, ethers ndi hydrocarbons.

- trans-2-penten-1-al;2-Pentanal;2-pentenal;gamma-methylcrotonaldehyde;Pent-2-enal;FEMA 3218;T2 PENTENAL;TRANS-2-PENTEN-1-AL; Kuwira kwa PENTENE-2-AL ndi pafupifupi 127 ℃ ndipo kachulukidwe ndi pafupifupi 0.803 g/cm.

-Ndi gulu losakhazikika komanso losavuta kulipanga potentha kutentha.

 

Gwiritsani ntchito:

- trans-2-penten-1-al;2-Pentanal;2-pentenal;gamma-methylcrotonaldehyde;Pent-2-enal;FEMA 3218;T2 PENTENAL;TRANS-2-PENTEN-1-AL;PENTENE-2-AL angagwiritsidwe ntchito ngati mankhwala reagents ndi intermediates zosiyanasiyana zochita mu organic kaphatikizidwe, monga asymmetric kaphatikizidwe, structural zimachitikira. ndi cycloaddition reactions.

-Amagwiritsidwanso ntchito popanga zonunkhira, mankhwala ndi mankhwala ophera tizilombo.

 

Njira Yokonzekera:

- trans-2-penten-1-al;2-Pentanal;2-pentenal;gamma-methylcrotonaldehyde;Pent-2-enal;FEMA 3218;T2 PENTENAL;TRANS-2-PENTEN-1-AL; Kukonzekera kwa PENTENE-2-AL nthawi zambiri kumatheka ndi transdehydration ya isoprenol. Izi zimachitika nthawi zambiri pamikhalidwe yofunikira, ndipo mwina chothandizira acidic kapena chothandizira choyambira chingagwiritsidwe ntchito.

 

Zambiri Zachitetezo:
