Nhanganyaya
(2E) -2-Butene-1,4-diol, inozivikanwawo se (2E) -2-Butene-1,4-diol, inhengo yehupenyu. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
(2E)-2-Butene-1,4-diol imvura isina ruvara kana kuti yakachenuruka yero ine hwema hwakakosha. Mushonga wayo wemakemikari ndeyeC4H8O2 uye uremu hwayo hwemamorekuru ndeye 88.11g/mol. Ine density ye 1.057g/cm³, nzvimbo yekuvira inosvika 225-230 madhigirii celsius, uye inonyungudika muzvinonyungudutsa zvakajairika semvura, ethanol uye ether.
Shandisa:
(2E) -2-Butene-1,4-diol ine zvakawanda zvinoshandiswa muindasitiri yemakemikari. Inogona kushandiswa seyepakati mune organic synthesis, yekugadzira resins yekugadzira, machira epamberi, madhayi uye epakati pemishonga uye mamwe makomisheni. Uye zvakare, inogona zvakare kushandiswa seyakanyungudika uye surfactant muindasitiri.
Kugadzirira nzira:
Kugadzirira kwe (2E) -2-Butene-1,4-diol kunogona kuitwa nenzira dzakasiyana-siyana. Imwe nzira yakajairika ndeyekuderedzwa kweButenedioic acid. Uku kudzikisira kunogona kushandisa chinodzikisira senge hydrogen uye catalyst, kana chinoderedza reactant senge sodium hydride kana sulfoxide.
Zvekuchengetedza
(2E) -2-Butene-1,4-diol isanganiswa yakachengeteka pasi pemamiriro ezvinhu ekushandiswa. Nekudaro, sechinhu chemakemikari, inogona kuramba ichikonzera kumwe kukuvadza kumuviri wemunhu. Kubata ganda, maziso kana kufema kwemhute kunogona kukonzera kushatirwa uye kurwadziwa kwemaziso. Nokudaro, kana uchibata uye uchishandisa (2E) -2-Butene-1,4-diol, matanho akakodzera ekuchengetedza anofanirwa kutorwa, zvakadai sekupfeka magirovhosi ekudzivirira uye midziyo yekudzivirira maziso, uye kuve nechokwadi chekushanda kwemhepo inotonhorera. Panguva imwecheteyo, inofanira kuchengetwa kure nemoto uye kudzivisa kusangana nemasimba ane oxidants. Tsvaga kurapwa nekukurumidza kana ukangobata kana kudya netsaona.
