heavy alkylated benzene (hab), which is a by-product in linear alkylbenzene (lab) production by uop process, is separated by distillation from lab and consists of a range of components such as polyalkylbenzenes, diphenylalkanes, alkyl tetralins, and alkylindans. the products of sulfonation of hab or its distillation cuts are of wide industrial applications such as emulsifiers, dispersants in lu...

In this study, linear alkyl-benzene calcium sulfonate nanoparticles were made using linear alkylbenzene. Calcium sulfonate nanoparticles are widely used as an additive in a variety of engine oils and have cleansing, anti-wear and anti-oxidant properties and anti-corrosion properties. In this method, a sulfonation set up was constructed and sulfonation reaction was carried out both directly and ...

Plutella xylostella cause considerable harm to the production of broccoli, Chinese cabbage, cabbage and cauliflower. The control P. is mainly performed using commercial insecticides, which have even led emergence resistant populations. Two easily available natural products found in different plants essential oil, thymol eugenol, stand up as possible novel agents this pest. In work a series alky...

Benzene, diphenyl sulfone (DPS), para-hydroxybiphenyl (PPP), ortho-hydroxybiphenyl (OPP), higher hydroxybiphenyls, and alkylated benzenes were found in a small lake receiving contaminated groundwater discharge from the Industri-Plex Superfund site (Woburn, MA) in the Aberjona watershed in eastern Massachusetts. All of these chemicals may derive from the former phenol manufacturing activities pr...

The chemical constituents within a snowpack can provide information about the atmosphere through which the snow was deposited. Valdez is located in south-central Alaska and has a high-latitude maritime climate, with annual snowfall typically exceeding 8 m within the city limits. Valdez is also the termination point of the trans-Alaska pipeline system, where tankers are loaded with crude oil fro...

The soil fungus Cladophialophora sp. strain T1 (= ATCC MYA-2335) was capable of growth on a model water-soluble fraction of gasoline that contained all six BTEX components (benzene, toluene, ethylbenzene, and the xylene isomers). Benzene was not metabolized, but the alkylated benzenes (toluene, ethylbenzene, and xylenes) were degraded by a combination of assimilation and cometabolism. Toluene a...

Mn(III)-mediated reactions of 2-isocyanobiaryls with 1,3-dicarbonyl compounds were described for the construction of 6-alkylated and 6-monofluoro-alkylated phenanthridines in moderate to good yields. The reaction involves formation of two new C-C bonds and one C-C bond cleavage.

n carbon.L However, no information on the stereochemistry of the alkylated products was ever reported. We now wish to report total stereospecificity in the formation and alkylation of the a-carbon, oxygen-dianions of aliphatic ketoximes. Treatment of acetoxime 1 with two equivalents of n-BuLi in THF at O°C for 15 minutes resulted in the formation of exclusively the x dianion 2, which upon deute...
