Butyl acetate, ti a tun mọ si butyl acetate, jẹ omi ti ko ni awọ ti o ni õrùn gbigbona ti ko ni itọ omi. Atẹle jẹ ifihan si awọn ohun-ini, awọn lilo, awọn ọna igbaradi ati alaye ailewu ti butyl acetate:

Didara:

- Irisi: Awọ sihin omi

- Molecular agbekalẹ: C6H12O2

- Iwọn Molikula: 116.16

- iwuwo: 0.88 g/mL ni 25 °C (tan.)

- Oju ibi farabale: 124-126 °C (tan.)

- Ojuami Iyọ: -78°C (tan.)

- Solubility: Die-die tiotuka ninu omi, tiotuka ni ọpọlọpọ awọn olomi Organic

Lo:

- Awọn ohun elo ile-iṣẹ: Butyl acetate jẹ ohun elo Organic pataki, eyiti o jẹ lilo pupọ ni awọn kikun, awọn aṣọ, awọn lẹ pọ, inki ati awọn aaye ile-iṣẹ miiran.

- Awọn aati Kemikali: O tun le ṣee lo bi sobusitireti ati epo ni iṣelọpọ Organic fun igbaradi ti awọn agbo ogun Organic miiran.

Ọna:

Igbaradi ti butyl acetate ni a maa n gba nipasẹ esterification ti acetic acid ati butanol, eyiti o nilo lilo awọn ohun mimu acid bi sulfuric acid tabi phosphoric acid.

Alaye Abo:

- Yago fun ifasimu, ifarakan ara ati jijẹ, ati wọ awọn ibọwọ aabo, awọn goggles ati awọn apata oju nigba lilo.

- Lo ni agbegbe ti o ni afẹfẹ daradara ati yago fun ifihan gigun si awọn ifọkansi giga.

- Tọju kuro lati ina ati awọn oxidants lati rii daju iduroṣinṣin wọn.

Ti tẹlẹ: Propyl acetate (CAS#109-60-4)
