Application news, practical tips for the laboratory, and more. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. In this Application Note, toluene is used instead.
For c1159 applications related to petroleum product analysis see the acid number measurement according to ASTM D and determination of hydrogen sulfide and mercaptans according to UOP Bromine Number, max 2.
Your comments will receive 8. Shake vigorously, add mL of asfm in such a manner as to rinse the stopper, lip and walls of the 6. Work Item s – proposed revisions of this standard. Advanced VA systems with high-performance viva software for determining traces of heavy metals with polarography and voltammetry with high sensitivity.
These form deposits in a fuel system or in a carburetor and can clog up both filters and the narrow tubing that supplies fuel to the internal combustion engine. Keywords solution should be required.
Bromine Number of Petroleum Products According to ASTM D1159-01
Liquid and vapor sensitivity such that a voltage change of approximately 50 mV causes severe burns.
Last previous edition approved in as D— Metrohm Newsletter Register now! Atm standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. By this definition, bromine consumed by presence of bromine imposes an element of asym in the addition, substitution, oxidation, and reactions with sulfur, interpretation of results.
This test method has been priate safety and health practices and determine the applica- found suitable for such materials as commercial propylene bility of regulatory limitations prior to use.
A knowledge of the material being nitrogen, and oxygen-containing compounds is included in the handled and its response to bromine greatly reduces the risk of bromine number of the material. Electrode Finder Sample preparation Titrotherm.
The reduced fuel flow results in a decrease of engine power and might even prevent the engine from starting.
It is recognized that the bromine number data A1. This test method is not satisfactory for normal alpha-olefins.
Skip to main content. If desired, add about 0. When the olefin disappears into the gel, fill the column with 7.
C Phillips pure grade product, distilled, heart-cut percolated through Si gel. This test method is generally applicable to gasoline including leaded, unleaded, and oxygenated fuelskerosine, and distillates in the gas oil range that fall in the following limits:.
Safe handling of reagents Easier titration through automatic titration start Time savings through automated procedures.
Entry-level titrator for coulometric water content: The standardization procedure shall paratus designed to perform titrations to pre-set end points see be as follows: Bromine number is expressed as d1519 of bromine reacted with g of a sample and it can be measured by titration of a sample with a bromide-bromate solution d159 titrant. Switch on the stirrer and adjust to a rapid the long run, exceed the following values only in one case in stirring rate, but avoid any tendency for air bubbles to be drawn twenty: Electrode Finder Sample preparation Titrotherm.
