UOP 704-70 is a laboratory test method for determining the equivalent weights of heavy organic amines by non-aqueous potentiometric titration. It is designed for technical teams that need a controlled analytical approach to characterize amine-based materials in petroleum, chemical, or refinery settings. By focusing on equivalent weight, the method helps support material comparison, product qualification, and routine quality assessment where heavy organic amines are part of the workflow. For laboratories selecting a UOP method for amine analysis, this document provides a clear and specific technical reference.

Purpose of UOP 704-70

The purpose of UOP 704-70 is to provide a standardized measurement approach for heavy organic amines using non-aqueous potentiometric titration. As a UOP Test Method, it supports analytical chemistry work where the equivalent weight of an amine sample is needed for evaluation or comparison. This makes it relevant to laboratory analysts and technical reviewers who handle specialty chemical or process-related samples. The method title indicates a focused determination rather than a broad compositional survey, which helps keep testing targeted and reproducible within a laboratory environment.

Laboratory use of UOP 704-70

UOP 704-70 is commonly suited to analytical laboratories supporting refinery, petrochemical, or specialty chemical operations where heavy organic amines must be examined consistently. It may be used by laboratory analysts, QA/QC personnel, and analytical chemists who need a dependable method for sample review, batch comparison, or technical documentation. Because the method is based on non-aqueous potentiometric titration, it fits workflows that require careful control of titration-based measurements for amine materials. It is especially relevant when internal teams need a recognized UOP method for method selection or data review.

Practical importance of UOP 704-70

The practical value of UOP 704-70 is its ability to support consistent laboratory results for heavy organic amines, which can matter in product qualification, quality verification, and technical comparison work. For organizations that depend on reliable amine characterization, a defined method helps reduce ambiguity in reporting and supports clearer internal decisions. Refineries, chemical producers, and testing labs may use it to align analytical records and maintain confidence in sample evaluation. In day-to-day work, that means better documentation, more comparable results, and a clearer basis for QA/QC review.
