Nhanganyaya

Fumaric acid. Iyi inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye transbutalic acid:

Hunhu:

- Transbutadiic acid ikristaro isina ruvara kana chena yakasimba ine pungent sour kuravira.

- Inonyungudika mumvura uye yakawanda organic solvents senge madoro uye ethers.

- Pakupisa kwepamusoro, transbutylic acid inoputsika kuti ibudise kabhoni dhaikisaidhi uye acetone.

Shandisa:

- Inoshandiswa zvakanyanya mukugadzirira kwepolyester resin kugadzirwa kwezvinhu zvakadai semachira, mapurasitiki, uye fiber.

Nzira:

- Transbutenedic acid inogona kuwanikwa nekuita kwebrominated butene uye sodium carbonate. Iyo chaiyo synthesis nzira inosanganisira akawanda matanho, kusanganisira kugadzirira kwebutene, bromination reaction, uye alkaline hydrolysis.

Zvekuchengetedza

- Transbutadiic acid inhengo inogumbura iyo inogona kukonzera kutsamwa uye kupisa mukubatana neganda nemaziso.

- Pfeka midziyo yekuzvidzivirira yakafanira senge magirovhosi, magirazi, uye zvipfeko zvekudzivirira panguva yekubata.

- Dzivisa kufema guruva rayo kana mhute uye inofanira kushanda munzvimbo ine mhepo inofefetera.

- Mitemo yemunharaunda uye nzira dzakachengeteka dzekushanda dzinofanira kuteverwa kana uchichengetedza uye uchibata komboni.
