Mankhwala maselo kapangidwe:

Chemical Properties:

1-Butanol ndi mtundu wa mowa wokhala ndi maatomu anayi a carbon omwe ali pa molekyulu. Mapangidwe ake a molekyulu ndi CH3CH2CH2CH2OH okhala ndi ma isomers atatu, omwe ndi iso-butanol, sec-butanol ndi tert-butanol. Ndi madzi opanda mtundu komanso fungo la mowa.
Imakhala ndi kuwira kwa 117.7 ℃, kachulukidwe (20 ℃) ​​kukhala 0.8109g/cm3, kuzizira ndi-89.0 ℃, kung'anima ndi 36 ~ 38 ℃, poziwotcha ndi 689F ndi index yowumitsa. kukhala (n20D) 1.3993. Pa 20 ℃, kusungunuka kwake m'madzi ndi 7.7% (polemera) pamene kusungunuka kwamadzi mu 1-butanol kunali 20.1% (kulemera kwake). Ndi miscible ndi Mowa, etha ndi mitundu ina ya zosungunulira organic. Itha kugwiritsidwa ntchito ngati zosungunulira zamitundu yosiyanasiyana ya utoto komanso zopangira popanga mapulasitiki, dibutyl phthalate. Angagwiritsidwenso ntchito popanga butyl acrylate, butyl acetate, ndi ethylene glycol butyl efa komanso ntchito ngati Tingafinye wa intermediates wa kaphatikizidwe organic ndi zamankhwala amuzolengedwa mankhwala komanso angagwiritsidwe ntchito popanga surfactants. Nthunzi yake imatha kupanga zosakaniza zophulika ndi mpweya ndi malire a kuphulika kukhala 3.7% ~ 10.2% (gawo la voliyumu).

Ntchito:

1. zomwe zimagwiritsidwa ntchito makamaka popanga phthalic acid, aliphatic dibasic acid ndi n-butyl phosphate plasticizers, zomwe zimagwiritsidwa ntchito kwambiri mumitundu yosiyanasiyana ya mapulasitiki ndi mphira. Ndiwonso zopangira zopangira butyraldehyde, butyric acid, butylamine ndi butyl lactate mu organic synthesis. Amagwiritsidwanso ntchito ngati dehydrating agent, anti-emulsifier ndi extractant of oil and grisi, mankhwala (monga maantibayotiki, mahomoni ndi mavitamini) ndi zonunkhira, komanso zowonjezera za zokutira za alkyd resin. Amagwiritsidwanso ntchito ngati zosungunulira za utoto wa organic ndi inki zosindikizira, komanso ngati dewaxing wothandizira. Amagwiritsidwa ntchito ngati zosungunulira kupatutsa potaziyamu perchlorate ndi sodium perchlorate, komanso amatha kulekanitsa sodium kolorayidi ndi lithiamu kolorayidi. Amagwiritsidwa ntchito kutsuka sodium zinc uranyl acetate precipitate. Amagwiritsidwa ntchito potsimikiza kwa colorimetric kudziwa arsenic acid ndi njira ya molybdate. Kutsimikiza kwa mafuta mu mkaka wa ng'ombe. Yapakatikati ya saponification ya esters. Kukonzekera kwa parafini-ophatikizidwa zinthu kwa microanalysis. Ntchito monga zosungunulira kwa mafuta, sera, utomoni, shellacs, chingamu, etc. Co-zosungunulira kwa nitro kutsitsi utoto, etc.

2. Chromatographic kusanthula zinthu muyezo. Ntchito colorimetric mtima wa arsenic asidi, zosungunulira kwa kulekana kwa potaziyamu, sodium, lithiamu ndi chlorate.
3. Chosungunulira chofunika kwambiri, chomwe chimagwiritsidwa ntchito mochuluka popanga urea-formaldehyde resins, cellulose resins, alkyd resins ndi utoto, komanso ngati wamba wosagwira ntchito diluent mu zomatira. Ndiwofunikanso mankhwala opangira mankhwala omwe amagwiritsidwa ntchito popanga plasticizer dibutyl phthalate, aliphatic dibasic acid ester ndi phosphate ester. Amagwiritsidwanso ntchito ngati dehydrating agent, anti-emulsifier ndi extractant mafuta, zonunkhira, maantibayotiki, mahomoni, mavitamini, ndi zina zotero, zowonjezera za utoto wa alkyd resin, co-solvent kwa utoto wa nitro spray, etc.
4. Zodzikongoletsera zosungunulira. Amagwiritsidwa ntchito makamaka ngati co-solvent mu misomali ya misomali ndi zodzoladzola zina kuti zigwirizane ndi zosungunulira zazikulu monga ethyl acetate, zomwe zimathandiza kusungunula mtundu ndikuwongolera kusinthasintha ndi kukhuthala kwa zosungunulira. Ndalama zowonjezera nthawi zambiri zimakhala pafupifupi 10%.
5. Itha kugwiritsidwa ntchito ngati antifoaming wothandizira pakuphatikiza kwa inki pakusindikiza pazenera.
6. Amagwiritsidwa ntchito pophika, pudding, maswiti.
