Summary: This standard specifies the method of free alcohol and essential oils and determination of total alcohol content Isolate and synthetic fragrances alcohol content by measuring the presence of sodium acetate, acetic anhydride ester value after acetylation sample to evaluate. This method is not applicable to oils containing more tertiary alcohol (such as linalool and terpineol), tertiary alcohol, tertiary alcohol can be a result of fully acetylated, nor to contain more phenols, lactones, aldehydes ketone enolate easy oils. Because in addition to free alcohol, these components will be acetylated.

Foreword

GB/T 14455 "spice general test method" consists of the following components. --- Part 1. Oil nomenclature; --- Part 3. spices dissolved in ethanol (mixed) to assess the degree; --- Part 5. Determination of acid value spices or acid content; --- Part 6. Determination of perfume ester value or ester containing an amount; --- Part 7. Determination of ester value assessment and the free alcohol and perfume total alcohol content after acetylation. This section GB/T 14455 Part 7. The partial modification of the use of ISO 1241.1996 "Determination of free alcohols and total alcohol content before and after the oil acetylated ester value assessment" and ISO 3794. 1976 "oils (containing tertiary alcohols) assessment of free alcohol content was measured after acetylation of ester value." This part of ISO 1241.1996 And ISO 3794. 1976 compared to the main technical differences are as follows. --- Remove the ISO 1241.1996 and ISO 3794. 1976 method of sampling; --- Increased the determination of the amount of alcohol and Appendix Isolate and synthetic fragrances containing A. This part is the "assessment ester value after acetylation oil Determination of free alcohols and total alcohol content" of GB/T 14455.7-1993, GB/T 14455.8-1993 "essential oils (containing tertiary alcohols) and free alcohol content was measured after acetylation ester value assessment", GB/T 14457.6- 1993 "Isolate and synthetic flavors, primary or secondary alcohols Determination acetylation method", GB/T 14457.8-1993 "Isolate and synthetic aroma Determination of material content of tertiary alcohols chloroacetyl - dimethyl aniline "consolidation and revision.

Determination of free alcohols and ester value after acetylation spices and Assess the total alcohol content

1 Scope

The first part of the method of the present GB/T 14455 requirements by measuring the presence of sodium acetate, acetylated with acetic anhydride ester samples before and after Value assessment methodology oil free alcohol and determination of the total alcohol content Isolate and synthetic fragrances containing alcohol content. This method does not apply to oils containing more tertiary alcohols (such as linalool and terpineol), tertiary alcohols because tertiary alcohol can not be fully acetylated; nor Contains more suitable phenols, lactones, aldehydes, ketones and easy enolate oils, because in addition to the free alcohol, these components will also be acetylated. GB/T 14455 in the second part of the provisions of this law by measured at N, N- dimethylaniline, with acetyl chloride and acetic anhydride acetic Acylated ester value before and after the samples to assess the essential oil free alcohol content and method of determination Isolate and synthetic fragrances containing alcohol content. This method is applicable to oils contain significant amounts of tertiary alcohols (such as linalool and terpineol), tertiary alcohols, does not apply to contain significant amounts of phenols, anthranilic Benzoic acid esters, lactones, aldehydes, oils and primary alcohols, secondary alcohols.
