Selelekela

2-Methyl-2-pentenic acid, e tsejoang hape e le butedic acid, ke motsoako oa manyolo. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea 2-methyl-2-pentenoic acid:

 

Boleng:

- 2-Methyl-2-pentenoic acid ke mokelikeli o mosehla o mosehla o se nang 'mala o nang le monko o kang oa litholoana.

- 2-Methyl-2-pentenoic acid e qhibiliha ka har'a metsi le metsoako ea tlhaho e kang joala le ethers.

- Ke motsoako o tsitsitseng o sa cheseng kapa o sa itšoare ka bohona mochesong o tloaelehileng le likhatello.

 

Sebelisa:

- 2-Methyl-2-pentenoic acid e sebelisoa haholo-holo ho lokiseng li-polymers tse sebetsang hantle tse kang liaparo tse khethehileng, li-adhesives, le li-sealants.

- Ke monomer ea bohlokoa ea bobeli e ka lokisoang ka polymerization ea butenic acid copolymers.

 

Mokhoa:

- 2-Methyl-2-pentenoic acid e ka lokisoa ka ho eketsa acid-catalyzed ea cyclohexene.

- Dimethyllithium le cyclohexene li itšoara ho fumana 2-methyl-1-cyclohexenylmethyllithium, ebe li hydrolyzed le acidified ho fumana 2-methyl-2-pentenoic acid.

 

Lintlha tsa Tšireletseho:
