Meanwhile, solvent-based solutions should be free from solvents that attack the ozone layer, and should instead be composed of water-soluble solvents, which exclude those most toxic for the user and most polluting for water, such as carbitol and
cellosolve.
WH-HP resin containing 45% solid was prepared by slowly adding butyl
cellosolve as a co-solvent and sufficient amount of preheated (70[degrees]C) deionized water into 100% solid WH-HP resin at about 90[degrees]C for 15-20 min under stirring.
Common VOCs like texanol, butyl
cellosolve, butyl carbitol, ethylene and propylene glycol are commonly used to help with film formation and drying, but also have the potential to create holes in the ozone layer and can cause headaches and other complaints for occupants, Zimmer notes.
Ethanol 2-ethoxy- also known by the trademark
cellosolve" or ethyl
cellosolve" is also a solvent used widely in commercial and industrial applications.
{The neutral detergent solution was prepared by dissolving 6.81 g of sodium borate decahydrate (Borax, [Na.sub.2][B.sub.4][O.sub.7].10[H.sub.2]O), 18.61g disodium ethylenediaminetetraacetate (EDTA, [C.sub.10][H.sub.14][N.sub.2][Na.sub.2][O.sub.8]), 30 g sodium lauryl sulphate neutral ([C.sub.10][H.sub.25]Na[O.sub.4]S), 10 ml 2-ethoxyethanol (ethylene glycol monoethyl ether,
cellosolve, [C.sub.4][H.sub.10][O.sub.2]) and 4.56 g disodium phosphate anhydrous ([Na.sub.2]HP[O.sub.4]) in distilled water while stirring and heating until complete solution was obtained.
It contains no ammonia, butyl
cellosolve or any other hostile chemicals.
Other ingredients to avoid for many reasons include diethanolamine (DEA), triethanolamine (TEA), 1,4-dioxane, ethoxylated alcohols, butyl
cellosolve (aka ethylene glycol monobutyl ether), and p-nonylphenol.
El material de herbario se restauro con una mezcla de butil
cellosolve y agua 1:4.
This paper covers recent a recent development in Head Space technology, the Dynamic Head Space with Purge & Trap, which ensures complete extraction of high boiling points solvents such as ethyl
cellosolve, propyl
cellosolve, toluene and methyl iso butyl ketone in addition to low boiling point solvents such as ethyl alcohol, ethyl acetate and methyl ethyl ketone.
