The reaction yield is about 2% of the radium weight.

The amount of product in a chemical synthesis is the reaction yield.

The reaction yield can range from 40% to 93% depending also on the desired substituent.

Microwave irradiation has been shown beneficial to reaction yields and times.

A typical reaction yield exceeds 95%.

The carbon highlighted in yellow is the main site of oxidation yielding the product at the right with a reaction yield of 59%.

Intermediates are isolated and tested to ensure their purity, and reaction yields are calculated at each step.

The synthetic strategies involving either 6-O protected or unprotected oxy-cellulose intermediates are compared in terms of reaction yields and product properties.

Developing effective and reliable continuous flow protocols to improve reaction yield, selectivity and minimize safety risks relative to batch conditions.

Photonuclear Reaction Yield Ratios in Tissues used as an Index of Abnormality.

In chemistry, yield (also called chemical yield or reaction yield) is the amount of product resulting from a chemical reaction.

The reaction yield stabilizes at equilibrium, but can be increased by removing the product from the reaction mixture or changed by increasing the temperature or pressure.

The reaction yield was only a few percent, and a more efficient route was found later by William F. Gorham at Union Carbide.

The classical Lemieux-Johnson oxidation often generates many side products, resulting in low reaction yields; however the addition of non-nucleophilic bases, such as 2,6-lutidine, can improve on this.

Interestingly, in all three works, addition of mono-N-protected amino acid (MPAA) such as N-acetyl glycine improves the reaction yields and enhances the regioselectivity.

Alcohols are commonly used as co-solvents or proton sources in SmI reductions, as immediate quenching of negatively charged intermediates with a proton source has proven beneficial for reaction yields.

For the unoptimized cross-metathesis reaction using the Grela catalyst at 0.01 M diene, the reaction yield was determined to be 82 percent after a reaction and workup time of 48 hours.

With a high yield (90%) ethylene oxide can be produced by treating calcium oxide with ethyl hypochlorite; substituting calcium by other alkaline earth metals reduces the reaction yield:

A simple test used to determine which state is involved is to make use of the diagnostic reaction of the triplet state with O, if the reaction yield is unchanged it indicates that the singlet state is involved.

Rhodocenium hexafluorophosphate forms after reaction of cyclopentadiene and rhodium(III) chloride hydrate in methanol following work-up with methanolic ammonium hexafluorophosphate; the reaction yield exceeds 60% with only 30 seconds of exposure to microwave radiation.

But after reaction development and optimization, the process team was able to improve the reaction yield to 93 percent after just 1 hour (plus 12 hours for workup and reactor cleaning time) at a diene concentration of 0.2 M. With these modifications, a 6-cubic meter reactor filled to 80% capacity afforded 799 kg of desired product.
