1.1.3 Chemical and physical properties of the pure substance From American Conference of Governmental Industrial Hygienists (1991) unless otherwise noted. (a) Description: Colourless, flammable liquid (b) Boiling-point: 145°C (Lide, 1997) (c) Melting-point: –64.6°C (Lide, 1997) (d) Solubility: Very slightly soluble in water (0.14% at 20°C); soluble in ethanol, diethyl ether and acetone (e) Vapo...

cis-polybutadiene was functionalized using in–situ generated dmd as oxidant and tetra-n-butyl ammonium bromide as phase transfer catalyst (ptc). the epoxidation process was investigated by 1hnmr spectroscopy. 1hnmr spectrum analysis of products confirms the absence of ring opening side products in epoxidation reaction. various factors such as reaction temperature, reaction time and the concentr...

Aims: To assess N-2-butyl cyanoacrylate injection’s effectiveness and safety in the treatment of gastric varix hemorrhage. Methods: Endoscopic with N-Butyl-2-cyanoacrylate injection was performed on 32 patients (21 males 11 females) variceal bleeding. The socioeconomic status patients, initial hemostasis, rebleeding rate, complications, mortality rate were all reviewed retrospectively. Patients...

Activators regenerated by electron transfer (ARGET) atom radical polymerization (ATRP)-based aqueous miniemulsion where the takes place in stabilized monomer droplets is described. In this work, we compared styrene, n-butyl methacrylate (nBMA) and tert-butyl (tBMA) investigated influence of their hydrophobicity on dispersity, molecular weight particle stability based partition coefficients (log...

Abstract Background Chinese sprangletop [ Leptochloa chinensis (L.) Nees] is an annual malignant weed, which can often be found in paddy fields. Cyhalofop-butyl a specialized herbicide utilized to control L. . However, many areas, has become tolerant this key due its continuous long-term use. Results In study, we (LC18002) and sensitive (LC17041) populations previously identified our laboratory...

t-Butyl alcohol is widely used in the manufacture of perfumes and a variety of cosmetics. It is also used as a raw material in the production of isobutylene, which may be used to produce methyl tertiary butyl ether, a common gasoline additive, or to produce butyl elastomers used in the production of automobile tires. The National Cancer Institute nominated t-butyl alcohol to the NTP for study a...
