Processing aids

Main production process

Triisobutyl phosphate is obtained from the reaction of phosphorus oxychloride

and isobutanol

Packaging and Storage

Package: Once the TIBP has been produced and refined, it is packaged into

suitable containers, such as Galvanized drums(200kg) or IBC drum(1000kg).

Storage: Store at room temperature, away from direct sunlight

Inspection process

1. Incoming inspection: The main raw materials, are inspected for their content, appearance and

other main properties.

2. Feeding inspection: The principle of raw material feeding is first-in-first-out, and the appearance

of the main raw materials is randomly inspected according to whether there is a big change in the

storage conditions before feeding.

3. Batch sampling in the production process: During the production process, the main indexes of

each batch of products: content and acid value will be examined three times in different time periods.

4. Storage Inspection: Each batch (10 tons) is inspected before storage.

5. Outbound inspection: According to the quantity demanded by customers, the products will be

sampled and inspected.

6. Pre-shipment inspection: According to customer’s requirement, third party inspection can be

carried out on the products before shipment.
