Foreword

This standard replaces GB 1900-2010 "Food Additives - Butylated Hydroxytoluene (BHT)". The main changes in this standard compared to GB 1900-2010 are as follows. ---The scope has been changed; ---Added odor; ---Added main content indicators and testing methods; ---Change "melting point (initial melting)" to "melting range"; ---Change "heavy metals (as Pb)" to "lead (Pb)"; ---The identification test has been modified. National Food Safety Standards Butylated hydroxytoluene (BHT), a food additive 1.Scope This standard applies to the alkylation reaction of p-cresol and isobutylene as raw materials using an acidic catalyst (concentrated sulfuric acid or p-toluenesulfonic acid). The food additive butylated hydroxytoluene (BHT) is obtained by distillation and recrystallization. 2.Chemical name, molecular formula, structural formula, and relative molecular mass 2.1 Chemical Name 2,6-Di-tert-butyl-p-methylphenol 2.2 Molecular Formula C15H24O 2.3 Structural Formula � � �� �� CH3 (H3C)3C OH C(CH3)3 2.4 Relative Molecular Mass 220.36 (based on 2022 international relative atomic mass)

Appendix A

Test methods A.1 Warning Some test procedures specified in the test methods may lead to hazardous situations. Operators should take appropriate safety and protective measures. A.2 General Provisions Unless otherwise specified, only reagents confirmed to be of analytical grade and Grade III water as specified in GB/T 6682 shall be used in the analysis. Unless otherwise specified, the standard titration solutions, standard solutions for impurity determination, preparations and products used in the test methods shall be in accordance with... Prepared in accordance with the provisions of GB/T 601, GB/T 602 and GB/T 603. A.3 Identification Test A.3.1 Ultraviolet Spectrophotometry A.3.1.1 Reagents and Materials Anhydrous ethanol. Superior grade. A.3.1.2 Instruments and Equipment A.3.1.2.1 UV-Vis spectrophotometer. with 1cm cuvette. A.3.1.2.2 Analytical balance. sensitivity 0.0001g. A.3.1.3 Analysis Steps A.3.1.3.1 Preparation of Sample Solution Weigh approximately 0.1 g of the sample, accurate to 0.0001 g, and place it in a 100 mL volumetric flask. Add an appropriate amount of anhydrous ethanol and sonicate in an ultrasonic water bath. Shake well for 2 minutes, cool, and bring to a final volume of 100 mL. Accurately measure 1.00 mL of the above solution into a 100 mL volumetric flask and dilute with anhydrous ethanol. Pour the mixture to the mark, shake well, and you're done. A.3.1.3.2 Measurement Using anhydrous ethanol as a reference, and a 1 cm cuvette, the sample solution was scanned in the wavelength range of 230 nm to 320 nm, and the wavelength at 278 nm was [missing value]. We should make the greatest possible use of strengths. A.3.2 Gas Chromatography A.3.2.1 Reagents and Materials Butylated hydroxytoluene (CAS. 128-37-0, molecular formula.
