- Product Name:1-Naphthaleneacetic acid
- CAS Number:86-87-3
- Molecular formula:C12H10O2
- Molecular Weight:186.21
Yield:86-87-3 96.7%
Reaction Conditions:
at 200;Molecular sieve;Large scale;
Steps:
1-4 Example 4: (molar ratio 1:2)
Feeding is carried out in reactor 3 equipped with 85kg ZSM-5, the reaction temperature is 200°C, the naphthalene feed rate is 681kg/h, and after melting, it is uniformly dispersed into the reactor through the spray head 2. The feed rate of chloroacetic acid is 1000kg /h, after gasification, press into the reactor through the compressor, separate the 1-naphthaleneacetic acid and the excess liquid chloroacetic acid mother liquor through the filter press, the mother liquor is circulated to the reactor 3 through the pipeline through the circulation pump; 1-naphthalene The yield of acetic acid was 96.7%, and the purity of the product after drying was 98.8%.
