These factors includes block-selective solvent
(DMF or 1,4-dioxane), the weight ratio of the selective solvent
to common solvent and initial concentration.
Method 8 utilizes the principle of selective solvent
absorption (SSA) to capture sulfur trioxide (SO3) and H2SO4 in an isopropyl alcohol (IPA) solution.
Furfural as a Selective Solvent
in Petroleum Refining.
On the other hand, the low tan [delta] I values observed for the extended sample in the interval -25[degrees]C to 40[degrees]C indicate that the selective solvent
oil probably eliminates the PEB rich part of the PEB/PS interphase, thereby reducing the dimensions of the latter.
Methylene chloride is a selective solvent
, removing only the caffeine and wax from the beans, leaving the coffee's flavor largely intact.
8 Mesophase Morphologies of Silicone Block Copolymers in a Selective Solvent
Studied by SAXS (Dietrich Leisner, Md.
Besides, by far, many factors (temperature, block length, the added selective solvent
content, the characteristics of the common solvent, etc.
Carbon dioxide is an extremely selective solvent
, it does not touch the carbohydrates (sugars and starch) and peptides (protein) which, during roasting, are converted to the compounds responsible for the flavor and aroma of brewed coffee.
Herein, we introduce the cinnamate group by grafting cinnamic acid onto PVA to prepare the amphiphilic graft polymer poly(vinyl cinnamates) (PVCi) and study its self-assembly behavior in selective solvent
The use of a selective solvent
for the minor component of polysty-rene-b-poly(methy1 methacrylate) (PS-PMMA) during annealing was investigated by Xu et al.
27 cm) were immersed in 25 ml of a selective solvent
for the major phase.
The polymer was divided into 13 fractions either by preparative size exclusion chromatography (SEC) or by selective solvent
extraction with hot p-xylene.
