LY/T 1645-2005Domestic camphor (English PDF)

Foreword

Appendix A, Appendix B, Appendix C and Appendix D of this standard are informative annexes.

This standard was proposed by the Institute of Chemical Industry of Forest Products of the Chinese Academy of Forestry.

This standard is under the jurisdiction of the Institute of Chemical Industry of Forest Products of the Chinese Academy of Forestry.

Introduction

This standard is a general standard for daily use of camphor products.

The main raw material used in daily camphor products is that the camphor is made from natural turpentine terpene after isomerization and addition and esterification of terpenes.

Chemical reaction (or direct hydration of terpenes), isothermal dehydrogenation, and a series of chemical reactions, such as rectification, crystallization, sublimation, etc.

The product obtained by the process is white powdery crystal, no optical activity, aromatic smell and cool feeling. The chemical name of synthetic camphor is anthrone-2.

The system was named 1,7,7-trimethyl-bicyclo[2,2,1]heptan-2-one. It differs from natural camphor in its ability to rotate. Camphor is recommended it is used as a green product for the production of insecticide products.

This standard applies to various types of daily camphor products made from synthetic camphor or natural camphor as the basic raw materials. These Brain products are mainly used for anti-mite, insect repellent, anti-corrosion, incense, etc. of clothes, fabrics, books, archives, paper, wood and the like.

3 Terms and definitions

The following terms and definitions apply to this standard.

Synthetic camphor or natural camphor as the basic material, if necessary, add a certain proportion of functional additives such as pigments, flavors or fragrances and then, through various processes such as stamping and forming, have various shapes and sizes, mainly used for clothes, fabrics, books, the camphor products of anti-mite, insect repellent, anti-corrosion, incense, etc. of files, paper, wood, etc.

In order to increase the visual aesthetics of the product, adjust the fragrance, add other functions, etc. according to different product requirements, but not for the human body A small amount of ingredients that are toxic, harmless, and have no adverse effects on the environment.

Note. Common chromatographic profiles and relative guarantees of several substances (such as naphthalene, p-dichlorobenzene, etc.) that may not be used as functional additives for adulteration.

See Appendix D for the time of stay.
