有机实验操作英语表达--后处理过程中常用的表述
过滤
The mixture was filtered through a Celite pad, and the filtrate was concentrated to
give crude product.
淬灭
The reaction mixture was quenched by the addition of saturated aqueous NH4Cl.
An aqueous solution of A (0.5 M, 10 mL) was added dropwise into the reaction mixture once the reaction mixture (solution or suspension) was warmed (or cooled) to -5 ℃or room temperature (ambient temperature).
The hot (or cold) reaction mixture (solution or suspension) was poured into water (ice water) or poured onto ice.
The reaction mixture (solution or suspension) was concentrated (distilled) under reduced pressure (in vacuum) or evaporated to remove MeOH (THF; DMF etc.) or excess SOCl2 (reagent). The residue (or the residual) was diluted with solvent and poured into water (ice water) or poured onto ice.
分液
After quenching the reaction, the reaction mixture was poured into separatory funnel
and separated.
磨碎
The residue was triturated with ether and filtered to afford a white solid.
在xxxx 中两相分开,隔开
The residue was partitioned between EtOAc (100 mL) and 1 N aq. HCl (50 mL). The organic layer was washed with H2O, dried (MgSO4) and evaporated to dryness.
EtOAc (100 mL) and 1 N aq. HCl (50 mL) were added to the residue, and the layers were separated.
静止固化
The crude product was purified by prep. HPLC to give compound 4 as a colorless
thick oil which was solidified on standing.
冻干机冻干
The white solid (105249x43A) was re-crystallized from water, dried by hyophilization
to give WP-100418 (105249x43B, 45.0 g, 39.2%) as a white solid.
纯化
过柱:
The crude product was chromatographed on silica gel (acetone/dichloromethane 10:90→10:80→10:70) to give compound 8 (0.282 g, 51%) as a white solid.
The crude product was purified by column chromatography on silica gel eluted with
acetone/dichloromethane (10:90~10:80~10:70) to give compound 8 (0.282 g, 51%) as a white solid.
制备的HPLC 纯化
be purified by preparative HPLC to afford/give/yield
制备的TLC 纯化
be purified by preparative TLC to afford/give/yield
重结晶
recrystallized from
调节pH
The pH was adjusted to around 9 by progressively adding solid NaHCO3.
The mixture was adjusted to pH 9 with solid NaHCO3.
酸化: be acidified to
碱化: be basified to
中和: be neutralized
萃取
The combined aqueous layers were extracted with EtOAc (100 mL×4) (or 4 times) to remove neutral impurities. The aqueous phase was acidified (or basified) with aqueous HCl (orNaHCO3) and extracted with CH2Cl2 (100 mL×5). The combined organic layers were dried over MgSO4 and concentrated.
浓缩
The mixture was evaporated to afford the crude product.
The mixture was concentrated to afford the crude product.
The solvent was removed to afford the crude product.
真空干燥
The precipitate was filtered and dried in vacuo (in/under vacuum; under reduced pressure).
