Nhanganyaya
2-Methyl-2-pentenic acid, inozivikanwawo sebutedic acid, inhengo yehupenyu. Iyi inotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye2-methyl-2-pentenoic acid:
Hunhu:
- 2-Methyl-2-pentenoic acid imvura isina ruvara kune yakachenuruka uye inonhuwa semichero.
- 2-Methyl-2-pentenoic acid inonyungudika mumvura uye organic solvents senge doro uye ethers.
- Ikomboni yakatsiga isingabatike kana kuzvipusha patembiricha yakajairwa uye kumanikidza.
Shandisa:
- 2-Methyl-2-pentenoic acid inonyanya kushandiswa mukugadzirira kwepamusoro-soro mapolymers akadai seyakakosha machira, adhesives, uye sealants.
- Yakakosha yechipiri monomer inogona kugadzirwa ne polymerization ye butenic acid copolymers.
Nzira:
- 2-Methyl-2-pentenoic acid inogona kugadzirirwa ne acid-catalyzed kuwedzera kwe cyclohexene.
- Dimethyllithium uye cyclohexene inobatwa kuti iwane 2-methyl-1-cyclohexenylmethyllithium, uye ipapo hydrolyzed uye acidified kuwana 2-methyl-2-pentenoic acid.
Zvekuchengetedza
- 2-Methyl-2-pentenoic acid chinhu chinotsamwisa chinogona kutsamwisa ganda nemeso, uye matanho anodiwa akadai sekupfeka magirovhosi ekudzivirira uye magirazi anodiwa panguva yekushandiswa.
- Haina kugadzikana kuchiedza uye tembiricha yakakwira, uye maitiro epolymerization anogona kuitika, saka kuratidzwa kwenguva refu kuchiedza chezuva kana kuchengetedza pakupisa kwakanyanya kunofanirwa kudzivirirwa.
- Panguva yekubata nekuchengetedza, inofanira kuchengetwa kure nezvinhu zvinopisa uye oxidizing agents kudzivirira njodzi yemoto kana kuputika.
- Paunenge uchibata 2-methyl-2-pentenoic acid, maprotocol akakodzera ekuyedza uye nhungamiro dzakachengeteka dzekushandisa dzinofanira kuteverwa. Kana pakaitika tsaona, matanho akakodzera ekukurumidzira anofanira kutorwa nekukasika uye rubatsiro rwezvechiremba rwenyanzvi runofanira kutsvagwa nekukasika.
