Abstract
A method for determining an amount of water in a sample includes the steps of providing a reagent including sulfur dioxide and/or a reaction product of sulfur dioxide and an alcohol and/or an amine, and further including a base, and a solvent; providing the sample including water; and titrating the sample with the reagent to determine the amount of water in the sample, wherein the reagent and/or the sample further includes a certain phenol compound.
Claims20
A method for determining an amount of water in a sample, said method comprising the steps of:
- A. providing a reagent comprising sulfur dioxide and/or a reaction product of sulfur dioxide and an alcohol and/or an amine;
- and further comprising a base;
- and a solvent;
- B. providing the sample comprising water;
- and
- C. titrating the sample with the reagent to determine the amount of water in the sample;
- wherein the reagent and/or the sample further comprises a phenol compound chosen from dihydroxybenzene, butylhydroxytoluol, butylhydroxyanisol, 2,2,5,7,8-pentamethyl-6-chromanol, alpha-tocopherol, and combinations thereof.
A method for determining an amount of water in a sample, said method comprising the steps of:
- A. providing a reagent comprising sulfur dioxide and/or a reaction product of sulfur dioxide and an alcohol and/or an amine;
- and further comprising a base;
- and a solvent;
- B. providing the sample comprising water;
- C. adding a source of iodine to the reagent and/or the sample;
- and
- D. titrating the sample with the reagent to determine the amount of water in the sample;
- wherein the reagent and/or the sample further comprises a phenol compound chosen from dihydroxybenzene, butylhydroxytoluol, butylhydroxyanisol, 2,2,5,7,8-pentamethyl-6-chromanol, alpha-tocopherol, and combinations thereof.
A method for determining an amount of water in a sample, said method comprising the steps of:
- A. providing a reagent comprising sulfur dioxide and/or a reaction product of sulfur dioxide and an alcohol and/or an amine;
- and further comprising diethylene glycol monoalkyl ether, and imidazole or a derivative thereof having the following structure (I):
- wherein each of R1, R2, and R3 is independently a hydrogen atom, a phenyl group, or a hydrocarbyl group, provided that R1, R2, and R3 are not all hydrogen atoms;
- B. providing the sample comprising water and xylene;
- and
- C. titrating the sample with the reagent to determine the amount of water in the sample;
- the reagent and/or the sample further comprises a phenol compound chosen from dihydroxybenzene, butylhydroxytoluol, butylhydroxyanisol, 2,2,5,7,8-pentamethyl-6-chromanol, alpha-tocopherol, and combinations thereof;
- and
- wherein the phenol compound is present in the reagent and/or the sample and in an amount of from about 5 to about 5000 parts by weight per one million parts by weight of the reagent and/or the sample.
