ʻIkepili kino huahana:
| inoa mea kūʻai | Propionic anhydride |
| Waiwai | ʻO ka wai ʻākala kala ʻole |
| ʻO ka mānoanoa (g/cm3) | 1.015 |
| Lae hehee(°C) | -42 |
| Puni paila (°C) | 167 |
| Kekahi uila (°C) | 73 |
| Hiki i ka wai (20°C) | hydrolyses |
| Pumi māhu(57°C) | 10mmHg |
| Ka hoʻoheheʻe | Hiki ke hoʻoheheʻe ʻia i ka methanol, ethanol, ether, chloroform a me ka alkali, decomposes i ka wai. |
Hoʻohana huahana:
1.Chemical synthesis: ʻO ka propionic anhydride he mea waiwai nui ia no ka nui o nā hopena kemika, i hoʻohana mau ʻia i nā esters, amides, acylation reactions a me nā mea ʻē aʻe.
2.Organic solvent: Hiki ke hoʻohanaʻia ka propionic anhydride e like me ka mea hoʻoheheʻe no ka hoʻoheheʻeʻana a me ka hoʻomākaukauʻana i nā meaʻala, resins, plastics a pēlā aku.
3.Pharmaceutical field: Hiki ke hoʻohanaʻia ka propionic anhydride i ka synthesis o kekahi mau lāʻau lapaʻau, e like me finasteride, chloramphenicol propionate a pēlā aku.
ʻIke palekana:
Hiki i ka 1.Propionic anhydride ke hoʻoulu i ka maka, ka hanu a me ka ʻili;holoi koke ma hope o ka pili ʻana.
2. E hoʻohana i nā mīkina lima pale, nā aniani a me nā masks i ka wā e hoʻohana ai i ka propionic anhydride a mālama i kahi wahi hana maikaʻi.
3. ʻO ka propionic anhydride ke ahi, e pale i ka pilina me ka wela a iʻole ka lapalapa ahi.
4. E kūʻai i loko o kahi pahu i hoʻopaʻa ʻia mai nā kumu o ke ahi a me nā mea oxidizing.
