Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 11135-1989 "Petroleum distillates and commercial aliphatic olefins - Determination of bromine number (potentiometric titration)", and
GB/T 11135-1989 main technical changes compared as follows.
--- Increased gasoline suitable types of instructions; the determination of the upper limit of the 90% distillation temperature of less than 205 ℃ petroleum fraction by "100gBr /
100g "to" 175g/100g "(see Chapter 1);
--- Given when bromine value is less than 1.0g/100g and 0.5g/100g, sample the applicable method (see Chapter 1);
--- Delete the words "This standard does not apply to added alcohols, ketones, ethers and amines additive oil" content (see the 1989 edition of the first
chapter);
--- To increase the content of the normative references (see Chapter 2);
--- Instrument section "ST (dead stop point) type titrator" to "Titrator"; and the elimination of GB/T 11135-1989
Standard ST (dead stop point) type titrator circuit diagram (see 61, 1989 version 5.1.);
--- Bromide - potassium bromate standard solution was added during the standard volumetric accuracy by the "5mL ± 0.05mL" to
"5mL ± 0.01mL" (see 7.4);
--- Starch solution preparation process is not added mercuric iodide reagent (see 78, 1989 version 7.3.);
--- Added "1,1,1-trichloroethane, methylene chloride instead of" content (see 7.12);
--- Increased cyclohexene and diisobutene reagent purification methods (see Chapter 8);
--- Precision numerical or algebraic representation are expressed, the abolition of graphics content; while increasing the deviation of the contents (see Chapter 11,
Chapter 10, 1989 edition);
--- Remove the "Report" Content section (see the 1989 version of Chapter 11);
--- Increase in Appendix A (normative) "was determined by potentiometric titration of bromine value results";
--- Deleted the relevant content in 1989 edition Appendix A to Fahrenheit units as shown in Table A.1, Table A.2, Figure A.2, Figure A.4;
And the contents of the 1989 version of Appendix A to Appendix B (see Appendix B, 1989 edition of Appendix A).
This standard uses redrafted law revision adopted ASTMD1159-2007 "petroleum distillates and commercial aliphatic olefins - Determination of bromine number
Potentiometric titration. "
The main difference between standard and ASTMD1159-2007 and for the following reasons.
--- This standard uses SI units only, remove Fahrenheit ASTMD1159-2007 Appendix B used in the table
Related content shown to conform to our standard rules for preparation;
--- Chapter 2 normative references cited in our respective national standards and industry standards for ease of use.
This standard by the National Standardization Technical Committee on products and lubricant oil (SAC/TC280) proposed.
This standard by the National Standardization Technical Committee of petroleum products lubricants oil and lubricants and fuels Technical Committee (SAC /
TC280/SC1) centralized.
This standard was drafted. China Petroleum & Chemical Corporation Research Institute of Petroleum.
Drafters of this standard. Ho Pei, Gao Ping.
This standard replaces the standards previously issued as follows.
--- GB/T 11135-1989.
Determination of petroleum distillates and commercial aliphatic olefins bromine value
Potentiometric titration
Warning. The application of this standard may involve some hazardous materials, operations and equipment, but not for all security related thereto
Issues recommendations. Users Before using this standard has the responsibility to develop appropriate security and protection measures, and determine the relevant regulatory restrictions applicable
Versatility.
1 Scope
This standard specifies the determination of petroleum distillates and commercial aliphatic olefins bromine number by potentiometric titration method.
This standard applies to the following sample bromine value determination.
a) 90% distillation temperature (using GB/T 6536 Determination) at 327 ℃ or less, and does not contain components lighter than isobutane petroleum fractions,
Such as. petrol (including leaded petrol, unleaded petrol and fuel oxygenates), kerosene and meet all conditions of Table 1 of distillate;
Table 1 measuring range petroleum fractions bromine value
90% distillation temperature/℃ Max bromine/(g/100g)
< 205 175
205 ~ 32710
b) bromine number between 95g/100g ~ 165g/100g of commercial olefins. Industrial olefin mixture is generally an aliphatic monoolefin,
The industrial propylene trimer, propylene tetramer, butene dimers and nonene mixture heptene and octene.
Note. Only the measured value of industrial precision bromine in 95g/100g ~ 165g/100g range olefins.
Bromine can reflect the amount of a substance can be used with bromine, but can not be used to identify the type of substance. Appendix A is given by potentiometric drops
Bromine value Titration result, only compound given in Appendix A is not available for the determination of olefin saturation.
When converting bromine bromine index value, to be multiplied by a factor 1000. But for the bromine value of less than 1.0g/100g of a mixture of petroleum hydrocarbons, is
A more precise measurement results, we recommend the use of GB/T 11136 or SH/T 0630 method; for bromine value of less than 0.5g/100g test
Thus, you can use GB/T 11136, SH/T 0630 or aromatic bromine index determination method method SH/T 1551, SH/T 1767 were measured.
Determination of attention when selecting the scope of each standard methods.
