In this article, we will explain what ASTM D2074-07 (2019) is, how it works, and what benefits it offers for your quality control and product development.

What are Fatty Amines?

Fatty amines are organic compounds that contain one or more nitrogen atoms attached to a long hydrocarbon chain. They are widely used as surfactants, emulsifiers, corrosion inhibitors, antistatic agents, biocides, and intermediates for various chemical reactions.

Fatty amines can be classified into four types based on the number of hydrogen atoms attached to the nitrogen atom: primary, secondary, tertiary, and quaternary. Primary amines have one hydrogen atom, secondary amines have two hydrogen atoms, tertiary amines have three hydrogen atoms, and quaternary amines have four hydrogen atoms.

The amine value of a fatty amine is a measure of its basicity or alkalinity. It is defined as the number of milligrams of potassium hydroxide (KOH) required to neutralize one gram of the fatty amine. The higher the amine value, the more basic the fatty amine is.

What is ASTM D2074-07 (2019)?

ASTM D2074-07 (2019) is a standard test method for determining the total, primary, secondary, and tertiary amine values of fatty amines by an alternative indicator method. This method uses an indicator solution that changes color when the fatty amine is neutralized by an acid solution.

The procedure involves dissolving a known amount of the fatty amine in chloroform and adding a phenyl isothiocyanate or salicylaldehyde reagent to form a colored complex with the primary and secondary amines. Then, a bromphenol blue or bromcresol green indicator solution is added to the mixture and titrated with a hydrochloric acid standard solution until the color changes from blue or green to yellow. The volume of acid used corresponds to the total amine value of the fatty amine.

To determine the primary amine value, the same procedure is repeated but without adding the phenyl isothiocyanate or salicylaldehyde reagent. The difference between the total amine value and the primary amine value gives the secondary plus tertiary amine value. To determine the secondary amine value, another sample of the fatty amine is treated with salicylaldehyde reagent and titrated with acid until the color changes from red to yellow. The difference between the total amine value and the secondary amine value gives the tertiary amine value.

What are the Benefits of ASTM D2074-07 (2019)?

ASTM D2074-07 (2019) offers several advantages over other test methods for measuring the amine values of fatty amines. Some of these benefits are:

• It is simple, fast, and accurate.

• It does not require expensive or sophisticated equipment.

• It can distinguish between primary, secondary, and tertiary amines.

• It can be applied to various types of fatty amines.

• It can help you ensure the quality and consistency of your products.

• It can help you optimize your processes and formulations.

What is Phenyl Isothiocyanate?

Phenyl isothiocyanate (PITC) is a chemical compound that has the formula C7H5NS. It is a colorless liquid with a pungent odor that is used as a reagent in various analytical and synthetic applications.

One of the main uses of phenyl isothiocyanate is in reversed phase high-performance liquid chromatography (HPLC), a technique for separating and identifying different components in a mixture. PITC can react with primary and secondary amines, such as amino acids and peptides, to form colored derivatives that can be detected by UV or fluorescence detectors.

Another use of phenyl isothiocyanate is in Edman degradation, a method for sequencing proteins by cleaving them one amino acid at a time from the N-terminus. PITC reacts with the N-terminal amino acid of a protein to form a phenylthiohydantoin (PTH) derivative that can be separated and identified by HPLC. The remaining peptide chain can then be subjected to another cycle of PITC reaction until the whole sequence is determined.

What is HPLC?

HPLC stands for high-performance liquid chromatography, which is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It is based on the principle of column chromatography, where a sample mixture is passed through a column filled with a solid material that selectively retains some components more than others.

HPLC differs from conventional liquid chromatography in that it uses high pressure to force the liquid mobile phase through the column at a faster rate and with smaller particles. This results in higher resolution, efficiency, and sensitivity of the separation. HPLC can also use different types of columns and mobile phases to achieve different modes of separation, such as reversed-phase, normal-phase, ion-exchange, size-exclusion, and affinity chromatography.

HPLC is widely used in various fields and applications, such as pharmaceuticals, biotechnology, environmental analysis, food safety, forensics, and clinical diagnostics. HPLC can separate and analyze a wide range of compounds, such as organic molecules, biomolecules, ions, and polymers.

How to Use HPLC with ASTM D2074-07 (2019)?

If you want to use HPLC with ASTM D2074-07 (2019), you need to follow some steps to prepare your sample, set up your instrument, perform the analysis, and interpret the results.

The first step is to prepare your sample by dissolving a known amount of the fatty amine in chloroform and adding the appropriate reagent for the type of amine value you want to measure. For example, if you want to measure the total amine value, you need to add phenyl isothiocyanate reagent to form a colored complex with the primary and secondary amines. Then you need to add an indicator solution that changes color when the fatty amine is neutralized by an acid solution.

The second step is to set up your HPLC instrument by choosing the suitable column, mobile phase, detector, and parameters. For example, if you want to use UV detection for the phenyl isothiocyanate derivatives, you need to select a reversed-phase column with a C18 stationary phase and a mobile phase composed of water and acetonitrile with an acidic modifier. You also need to set the wavelength of the detector at 254 nm and the flow rate of the mobile phase at 1 mL/min.

The third step is to perform the analysis by injecting your sample into the HPLC system and recording the chromatogram. The chromatogram shows the peaks corresponding to the different components in your sample based on their retention time and absorbance. You can use external or internal standards to calibrate your system and calculate the concentration of each component.

The fourth step is to interpret the results by comparing your data with ASTM D2074-07 (2019) specifications and calculations. You can use the volume of acid used in the titration and the concentration of your sample to calculate the amine value of your fatty amine according to the formula given in ASTM D2074-07 (2019). You can also compare your results with other standards or specifications that require ASTM D2074-07 (2019) test methods.
