BACKGROUND A sampling campaign of indoor air was conducted to assess the typical concentration of indoor air pollutants in 8 National Libraries and Archives across the U.K. and Ireland. At each site, two locations were chosen that contained various objects in the collection (paper, parchment, microfilm, photographic material etc.) and one location was chosen to act as a sampling reference locat...

The conversion of biomass into chemicals, fuels and energy using the bio-refinery concept has attracted lot of attention. In particular, lignocellulosic biomass, consisting of cellulose (ca. 50%), hemicellulose (ca. 30%) and lignin (ca. 20%) is of special interest because it is non-edible and in plentiful supply. Hemicellulose is a heterogeneous polymer, made up of C5 and C6 sugars (such as xyl...

For the first time, we evidence experimentally that furfural derivatives can react as dienes in Diels–Alder cycloadditions.

Furfural is a platform molecule that can be catalytically converted using cascade series of reactions into levulinic esters, essential compounds used as fuel additives. Bifunctional catalysts containing Lewis and Brønsted acid sites such zeolites are commonly for these conversions. However, microporous often present diffusional restriction due to the size similarity furfural other molecules zeo...

Bacillus coagulans P38 is an efficient polymer-grade l-lactic acid producer from a cellulosic carbon source. Here, the draft 3.37-Mb genome sequence of this potential strain may provide useful information to further improve the strain performance for higher titers and, importantly, to understand the mechanism of its high tolerance for 2-furfural.

4-Nitrobenzylidenedimethylsulfurane 4-Nitrobenzylidenedimethylsulfurane, a semi-stabilized sulfonium ylide has been generated by the attack of methylsulfinyl carbanion in dimethyl sulfoxide and reacted with a series of substituted benzaldehydes, furfural and benzylideneacetophenone to afford <mns-l,2-disubstituted epoxides in fair to good yields. The structural assignments of the products are b...

The title compound, C(12)H(11)NO(4)S, is a Schiff base derived from the condensation reaction of equimolar quanti-ties of sulfamide and furfural. The mol-ecule has a trans configuration with respect to the imine C=N double bond. The N atom is involved in an inter-molecular O-H-N hydrogen bond.

The title compound, C(14)H(11)ClO(2), was prepared from 4-chloro-hypnone and 5-methyl-furfural by an aldol condensation reaction. The dihedral angle formed between the two benzene rings is 7.71 (2)°. The crystal structure is stabilized by C-H⋯O inter-actions.
