genel bakış

Petrol eteri alifatik hidrokarbonlardan oluşan ve 35‒60 ° C aralığında kaynayan petrol fraksiyonudur; yaygın olarak bir laboratuvar solventi olarak kullanılır. İsmine rağmen, petrol eteri bir eter olarak sınıflandırılmamıştır; Terim sadece mecazi olarak kullanılır, aşırı hafifliği ve oynaklığı gösterir.
Bu, 70 ° C'ye 30 ° C bir kaynama noktasına sahip bir petrol fraksiyonu ve esas olarak pentan C 5H 1 2 ve heksan C 6H 1 ila 4 oluşmaktadır. Dikkat, kimyasal isimde bir eter olmadığından ödenir. Ateş yakmak kolaydır. Özgül ağırlık 0.66 - 0.68. Solvent olarak kullanılır.
