Intangiriro

Butyl acetate, izwi kandi nka butyl acetate, ni amazi atagira ibara afite impumuro mbi idashonga amazi. Ibikurikira nintangiriro kumiterere, ikoreshwa, uburyo bwo gutegura namakuru yumutekano ya butyl acetate:

Ubwiza:

- Kugaragara: Amazi adafite ibara

- Inzira ya molekulari: C6H12O2

- Uburemere bwa molekuline: 116.16

- Ubucucike: 0,88 g / mL kuri 25 ° C (lit.)

- Ingingo yo guteka: 124-126 ° C (lit.)

- Ingingo yo gushonga: -78 ° C (lit.)

- Gukemura: Gushonga buhoro mumazi, gushonga mumashanyarazi menshi

Koresha:

- Imyitwarire yimiti: Irashobora kandi gukoreshwa nka substrate na solvent muri synthesis organique mugutegura ibindi bintu kama.

Uburyo:

Gutegura acetate ya butyl mubisanzwe tuboneka muguhindura aside acetike na butanol, bisaba gukoresha catisale ya acide nka acide sulfurike cyangwa aside fosifori.

Amakuru yumutekano:

- Irinde guhumeka, guhuza uruhu no kuribwa, kandi wambare uturindantoki turinda, amadarubindi n'ingabo zo mu maso mugihe ukoresha.

- Koresha ahantu hafite umwuka uhagije kandi wirinde kumara igihe kinini uhura cyane.

- Bika kure yumuriro na okiside kugirango umenye neza.

Mbere: Propyl acetate (CAS # 109-60-4)

Ibikurikira: Cinnamyl acetate (CAS # 103-54-8)
