0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institution on 19 December 1975, after the draft finalized by the Organic Chemicals ( Miscellaneous ) Sectional Committee ha.d been approved by the Chemical Division Council.

0.2 Triethanolamine is used as an intermediate in the manufacture of surface active agents, textile specialities, antirust compounds, waxes, polishes, herbicides, petroleum demulsifiers, toilet goods, cement additives, and cutting oils. It also finds extensive use in the manufacture of synthetic resins; as solvent for casein, shellac and dyes; for increasing the penetration of organic liquids into wood and paper; in the production of lubricants for textile industry; and in making emulsions with mineral and vegetable oils, paraffin and waxes.

0.3 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accord- ance with IS : 2-1960”. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

1. SCOPE

1.1 This standard prescribes the requirements and the methods of sampling and test for triethanolamine, technical.

2. REQUIREMENTS

2.1 Description - The material shall consist mainly of triethanolamine [N (CH&H~OH)~] and may contain small amounts of monoethanol- amine or diethanolamine or both. It shall be a bright clear liquid free from visible impurities.
