Oil sands may be surface mined and transported to a treatment area or may be treated directly by means of an in situ process of oil sand deposits that are located too deep for strip mining. A bitumen recovery process may be used to extract bitumen from oil sands. Specifically, the bitumen recover process involves a step of treating oil sands with a propylene oxide capped glycol ether described by the structure:
RO—(C2H4O)n—CH2CH(CH3)OH
wherein R is a linear, branched, or cyclic alkyl, phenyl, alkyl phenyl group and n is 1 to 10.
油砂可在地表开采并运往处理区,也可通过原地工艺直接处理太深而无法剥离开采的油砂矿藏。

其中 R 为线性、支链或环状烷基、苯基、烷基苯基,n 为 1 至 10。
