Transforming Methyl Levulinate into Biosurfactants and Biolubricants by Chemoselective Reductive Etherification with Fatty Alcohols.

Andrea Garcia-Ortiz et al.

ChemSusChem, 13(4), 707-714 (2020-01-09)

Biomass-derived surfactants with very good surface tension and critical micellar concentration properties were obtained by conversion of methyl levulinate into methyl 4-alkoxypentanoates through reductive etherification with aliphatic alcohols. Among different bifunctional acid/metal catalysts best results were obtained with Pd on

Metabolites from the biodegradation of di-ester plasticizers by Rhodococcus rhodochrous.

Sandro Nalli et al.

The Science of the total environment, 366(1), 286-294 (2005-12-01)

The plasticizers di-2-ethylhexyl phthalate (DEHP) and di-2-ethylhexyl adipate (DEHA) are ubiquitous in the environment and undergo partial biodegradation in the presence of soil micro-organisms. The validity of a proposed pathway for the degradation of these plasticizers by Rhodococcus rhodochrous has

Epoxidation using molecular oxygen in flow: facts and questions on the mechanism of the Mukaiyama epoxidation

Vanoye L, et al.

Catalysis Science & Technology, 6, 4724-4732 (2016)

E-2-ethylhexenal, E-2-ethyl-2-hexenol, mellein, and 4-hydroxymellein in Camponotus species from Brunei.

Heather L Voegtle et al.

Journal of chemical ecology, 34(2), 215-219 (2008-01-24)

E-2-ethyl-2-hexen-1-ol (1), mellein (4), and 4-hydroxymellein (5) were identified as the major volatile compounds in the head and/or thorax of Camponotus quadrisectus. Neither 1 nor 5 have been previously detected in insects. Also identified were small amounts of m-cresol (2)

Effects of di-(2-ethylhexyl) phthalate and four of its metabolites on steroidogenesis in MA-10 cells.

Carlie D Piché et al.

Ecotoxicology and environmental safety, 79, 108-115 (2012-01-13)

Phthalate plasticizers are used in the plastics industry to aid in processing and impart flexibility to plastics. Due to the broad use of plastics, and the tendency of plasticizers to leach out of polymers, plasticizers have become ubiquitous in the

Continuous catalytic ?one-pot? multi-step synthesis of 2-ethylhexanal from crotonaldehyde

Seki T, et al.

Chemical Communications (Cambridge, England), 3562-3564 (2007)

Bis(2-t-butylphenyl) phosphonoacetamides for the highly cis-selective synthesis of α, β-unsaturated amides

Ando K, et al.

Tetrahedron Letters, 50, 5689-5691 (2009)

C-alkylation of chiral tropane- and homotropane-derived enamines.

David M Hodgson et al.

The Journal of organic chemistry, 78(4), 1508-1518 (2013-01-30)

The synthesis and alkylation of chiral, nonracemic tropane- and homotropane-derived enamines is examined as an approach to enantioenriched α-alkylated aldehydes. The two bicyclic N auxiliaries, which differ by a single methylene group, give opposite senses of asymmetric induction on alkylation

Factors affecting the selectivity of air oxidation of 2-ethyhexanal, an α-branched aliphatic aldehyde

Lehtinen C and Brunow G

Organic Process Research & Development, 4, 544-549 (2000)

[Effect of 2-ethyl-2-ene-1-al and analogous compounds on the growth and ultrastructure of fungi].

G Casperson et al.

Journal of basic microbiology, 26(5), 259-269 (1986-01-01)

Analogs of the natural substance (E)-hex-2-en-1-al which occurs naturally in green plants and is known to have microbiocidal properties were synthesized and studied with respect to their antifungal properties. Saturated and unsaturated aldehydes, alcohols, carbon acids and enolacetate were tested

Glutathionylation and Reduction of Methacrolein in Tomato Plants Account for Its Absorption from the Vapor Phase.

Shoko Muramoto et al.

Plant physiology, 169(3), 1744-1754 (2015-07-15)

A large portion of the volatile organic compounds emitted by plants are oxygenated to yield reactive carbonyl species, which have a big impact on atmospheric chemistry. Deposition to vegetation driven by the absorption of reactive carbonyl species into plants plays

Renewable lubricants with tailored molecular architecture.

Sibao Liu et al.

Science advances, 5(2), eaav5487-eaav5487 (2019-02-13)

We present a strategy to synthesize three types of renewable lubricant base oils with up to 90% yield using 2-alkylfurans, derived from nonfood biomass, and aldehydes, produced from natural oils or biomass through three chemistries: hydroxyalkylation/alkylation (HAA), HAA followed by

Absorption and biodegradation of hydrophobic volatile organic compounds: determination of Henry's constants and biodegradation levels.

G Darracq et al.

Water science and technology : a journal of the International Association on Water Pollution Research, 59(7), 1315-1322 (2009-04-22)

Biodegradation of three volatile organic compounds (VOCs) was studied. Toluene, dimethylsulphide (DMS), and dimethyldisulphide (DMDS) were introduced into flasks filled with emulsions of Di-2-EthylHexylAdipate (DEHA) in water, containing biomass (activated sludge). The VOC concentrations were analysed in the gas, organic

The effect of feeding di-(2-ethylhexyl) phthalate and related compounds on lipids in the laying hen.

D L Wood et al.

Poultry science, 63(3), 469-477 (1984-03-01)

Di-(2-ethylhexyl) phthalate (DEHP) and three structurally related side-chain analogs were fed to laying hens to determine relationships of structure to effects on lipid metabolism. Hubbard broiler breeder hens were fed either a standard laying mash control diet or the control
