2. Fractionation - Wikipedia

   en.wikipedia.org/wiki/Fractionation

   [1] [2] Fractions are collected based on differences in a specific property of the individual components. A common trait in fractionations is the need to find an optimum between the amount of fractions collected and the desired purity in each fraction. Fractionation makes it possible to isolate more than two components in a mixture in a single run.

3. Fraction (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Fraction_(chemistry)

   A fraction in chemistry is a quantity collected from a batch of a substance in a fractionating separation process. In such a process, a mixture is separated into fractions, which have compositions that vary according to a gradient. A fraction can be defined as a group of chemicals that have similar boiling points.

4. Quotition and partition - Wikipedia

   en.wikipedia.org/wiki/Quotition_and_partition

   Quotition is the concept of division most used in measurement. For example, measuring the length of a table using a measuring tape involves comparing the table to the markings on the tape. This is conceptually equivalent to dividing the length of the table by a unit of length, the distance between markings.

5. Lever rule - Wikipedia

   en.wikipedia.org/wiki/Lever_rule

   In chemistry, the lever rule is a formula used to determine the mole fraction (x i) or the mass fraction (w i) of each phase of a binary equilibrium phase diagram.It can be used to determine the fraction of liquid and solid phases for a given binary composition and temperature that is between the liquidus and solidus line.

6. Mole fraction - Wikipedia

   en.wikipedia.org/wiki/Mole_fraction

   It is a dimensionless quantity with dimension of / and dimensionless unit of moles per mole (mol/mol or mol ⋅ mol-1) or simply 1; metric prefixes may also be used (e.g., nmol/mol for 10-9). [5] When expressed in percent , it is known as the mole percent or molar percentage (unit symbol %, sometimes "mol%", equivalent to cmol/mol for 10 -2 ).

   At the end of the third quarter of 2012, Latham had more than $1.5 million in cash on hand, compared with $226,000 for Boswell. Crossroads GPS , a conservative advocacy group backed by Karl Rove, the NRCC and Latham's campaign ran ads hitting Boswell for his votes in favor of TARP, the stimulus package and Obamacare.

   The large, flightless creatures are the second-largest living bird, with an average height of more than 5 1/2 feet. Females, like the ones that escaped in South Carolina, can weigh more than 130 ...

9. Fractional distillation - Wikipedia

   en.wikipedia.org/wiki/Fractional_distillation

   The calculations involved in the design of petroleum fractionation columns require in the usual practice the use of numerable charts, tables, and complex empirical equations. In recent years, however, a considerable amount of work has been done to develop efficient and reliable computer-aided design procedures for fractional distillation.
