in vacuo การใช้

• The solvents and excess reagent were removed " in vacuo ".
• The pure drug is then collected by vacuum filtration and dried in vacuo.
• It may be dehydrated " in vacuo ", by reaction with acetic anhydride, or by heat.
• For true ( " in vacuo " ) relative density calculations air pressure must be considered ( see below ).
• Vinyl pressings were made with stampers from master cuts that were electroplated " in vacuo " by means of gold sputtering.
• For true ( " in vacuo " ) specific gravity calculations, air pressure must be considered ( see below ).
• When allyl bromide reacted with HBr " in vacuo " ( in the absence of homolytic cleavage and creating the peroxide radical.
• The problem was that these calculations assumed what today is called an " in vacuo " trajectory  they made no allowance for air resistance against the projectile.
• Among the questions he discussed are : " An Deus extra coelum, vel in vacuo intra coelum esse possit, aut ante mundi creationem alicubi fuerit ".
• Robert Hooke had theorised that planets, moving in vacuo, describe orbits around the Sun because of a rectilinear inertial motion by the tangent and an accelerated motion towards the Sun.
• It is available in anhydrous form, and if water has been absorbed it is easy to dry by heating at 100 癈 for two hours " in vacuo ".
• Shouldn't the scientific community redefine the metre so that the speed of light in vacuo is " exactly " 3 x 10 ^ 8 ms ^-1?
• An enrichment lien, the court noted, could not exist " in vacuo "; it served merely to strengthen an underlying cause of action based on unjust enrichment.
• It is stable in the air for several days when stored from light, and is stable up to several months if dried in vacuo over potassium hydroxide, decomposing into a white paste.
• An economic one-pot reaction is heating the salt of propionic acid with ethanolamine at 200 癈 in vacuo in the presence of zinc chloride yielding 82 % 2-ethyl-2-oxazoline.
• Less drastic reaction conditions require the dehydration of the N-( 2-hydroxyethyl ) propionamide in vacuo in the presence of iron ( III ) chloride, which delivers the product in 90 % yield.
• The plant yields 0.3 % of a dark green petroleum ether extract, which, on steam distillation in vacuo, yields 10 to 15 per cent of a fairly viscous, yellowish, volatile oil.
• However, the period of the pendulum was found to be temperature dependent below the transition temperature, tending toward the period " in vacuo " at the lowest temperatures ( those approaching absolute zero ).
• With an air dielectric cable, which is approximated to with low-loss cable, the velocity of propagation is very close to " c ", the speed of light " in vacuo ".
• Paragraph 13 states that the weight " in vacuo " of this standard shall be called the Imperial Standard Pound, and that all other weights mentioned in the act and permissible for commerce shall be ascertained from it alone.
