Properties and stability

Prevent contact with eyes, skin and clothing, and prevent accidental ingestion and inhalation.

Storage method

Store in a cool, dry place. Keep lid tightly closed when not in use.

Synthesis method

Benzene sulfonic acid is produced by the sulfonation of benzene, and then reacted with benzene. First, heat 100% sulfuric acid to 130ºC, and introduce benzene vapor into it. After 20 minutes, the reaction temperature rises to 180ºC, and then after 2 hours, The reaction temperature is increased to 205~215ºC and the reaction is continued for 10~12h. After the reaction stops, cool, pour into water, filter, wash and dry to obtain the finished product.

Purpose

Used in organic synthesis as plasticizer and acaricide.

Used as pharmaceutical and pesticide intermediates.
