[求助] 帮忙翻译两个单词

To a solution of ketoester 1 (10 mmol) in abs. benzene (30 mL)
sodium (0.24 g, 10.5 mmol) was added, and the mixture was stirred
for 3–4 h until sodium dissolved.
这句话中abs. benzene是什么意思？
To a suspension of cyclopentenone 4h (0.10 g, 0.30 mmol) in a
mixture of 10%-solution of KOH in water (1 mL) and ethanol (1 mL)
corresponding aldehyde (0.45 mmol) was added. The reaction mixture
was refluxed for 2 h, poured into water (10 mL), the precipitate
was filtered off and washed with water (2 × 10 mL) and petrol. ether
(2 × 10 mL) and recrystallized from the ethanol-water mixture. In
the case of ferrocenaldehyde the reaction mixture was poured
into water (10 mL) and extracted with ethyl acetate (2 × 20 mL),
the combined extracts were washed with water (2 × 20 mL), dried
with magnesium sulfate and evaporated in vacuum, the residue
was purified by column chromatography eluting with petrol.
ether/ethyl acetate 6:1.
