Iine poindi yekubikira yekuve 117.7 ℃, density (20 ℃) ​​iri 0.8109g/cm3, nzvimbo yechando iri-89.0 ℃, flash point iri 36 ~ 38 ℃, self-ignition point iri 689F uye refractive index. kuva (n20D) 1.3993. Pa20 ℃, kunyungudika kwayo mumvura i7.7% (nehuremu) nepo kunyungudika kwemvura mu1-butanol kwaive 20.1% (nehuremu). Inosanganiswa ne ethanol, ether uye mamwe marudzi e organic solvents. Inogona kushandiswa sezvinonyungudutsa zveakasiyana pendi uye iyo mbishi yekugadzira iyo plasticizers, dibutyl phthalate. Inogona zvakare kushandiswa kugadzira butyl acrylate, butyl acetate, uye ethylene glycol butyl ether uye zvakare inoshandiswa seinobvisa yepakati pe organic synthesis uye biochemical zvinodhaka uye inogona zvakare kushandiswa mukugadzira surfactants. Chipfunga chayo chinogona kuumba misanganiswa inoputika nemhepo ine muganho wekuputika uri 3.7% ~ 10.2% (chikamu chevhoriyamu).

Application:

1. inonyanya kushandiswa mukugadzirwa kwephthalic acid, aliphatic dibasic acid uye n-butyl phosphate plasticizers, iyo inoshandiswa zvakanyanya mumhando dzakasiyana-siyana dzepurasitiki uye zvigadzirwa zverubha. Iri zvakare raw material yekugadzira butyraldehyde, butyric acid, butylamine uye butyl lactate mune organic synthesis. Inoshandiswawo se dehydrating agent, anti-emulsifier uye extractant yemafuta nemafuta, zvinodhaka (zvakadai semishonga inorwisa mabhakitiriya, mahomoni uye mavitamini) uye zvinonhuwira, uye kuwedzera kwealkyd resin coating. Inoshandiswawo se solvent ye organic dhayi uye kudhinda ingi, uye se dewaxing agent. Inoshandiswa se solvent kuparadzanisa potassium perchlorate uye sodium perchlorate, inogonawo kuparadzanisa sodium chloride uye lithium chloride. Inoshandiswa kugeza sodium zinc uranyl acetate precipitate. Inoshandiswa mu colorimetric kutsunga kuona arsenic asidhi ne molybdate nzira. Kutsunga kwemafuta mumukaka wemhou. Pakati pe saponification ye esters. Kugadzirira kweparafini-yakaiswa zvinhu zve microanalysis. Inoshandiswa sechinhu chinonyungudutsa chemafuta, wax, resin, shellacs, gums, etc. Co-solvent ye nitro spray pendi, nezvimwewo.

2. Chromatographic analysis standard zvinhu. Inoshandiswa pakusarudza colorimetric ye arsenic acid, solvent yekuparadzanisa potassium, sodium, lithium uye chlorate.
3. Mushonga unokosha, unoshandiswa muhuwandu hwakawanda mukugadzirwa kweurea-formaldehyde resins, cellulose resins, alkyd resins uye pendi, uyewo sechinhu chinowanzoitwa diluent muzvinyorwa. Iyo zvakare yakakosha kemikari mbishi zvinhu inoshandiswa mukugadzira plasticizer dibutyl phthalate, aliphatic dibasic acid ester uye phosphate ester. Inoshandiswawo senge dehydrating agent, anti-emulsifier uye inobvisa mafuta, zvinonhuhwirira, mishonga inorwisa mabhakitiriya, mahormone, mavhitaminzi, nezvimwewo, kuwedzera kwe alkyd resin pendi, co-solvent ye nitro spray pendi, nezvimwe.
4. Cosmetic solvent. Inonyanya kushandiswa se-co-solvent mune nail polish uye zvimwe zvizoro kuti zvienderane neiyo huru solvent senge ethyl acetate, iyo inobatsira kunyungudutsa ruvara uye kugadzirisa kushata uye viscosity ye solvent. Mari yekuwedzera kazhinji inenge 10%.
5. Inogona kushandiswa seantifoaming agent ye inki blending mukudhinda screen.
6. Inoshandiswa mune zvakabikwa, pudding, candy.
