Introduction

P-Tert Butyl Catechol is usually available as a solid cast, crystal, 85% solution in methanol or water. Special solutions can be prepared upon request. This catalogue provides specifications and information on handling, storage and product uses. Additional information is available upon request. The information provided here is given in good faith and is the best available to our knowledge. We assume no liability, however, we guarantee that we will meet our product specifications.

Product Specifications

P-Tert Butyl Catechol / 4-Tert Butyl Catechol / TBC / Tert Butyl Catechol

Common name

P-Tert Butyl Catechol

Chemical Name 4-Tertiary Butyl Ortho Di-Hydroxy Benzene
Empirical Formula C6H3OH2C4H9
Molecular Weight 166
Form White to tan, turning brown on standing
Assay 98% Minimum
Set Point 50 ~ 52 C
Boiling Point, 760 mm HG 284 C
Flash Point 130 C
Solubility Readily soluble in Diethyl Ether, Acetone, Methanol. Moderately soluble in Benzene, Toluene, Chloroform, and Carbon Tetrachloride

A second order transition point often occurs approximately 10 C below the primary set point. P-TBC is a relatively low melting solid & often turns to a partial liquid if exposed to high temperatures during the course of transportation and storage. The liquefied part settles at the bottom of the container, thus reducing the set point.

P-Tert Butyl Catechol Crystals (Non Uniform, Crushed Granular lumps)

We offer a unique form of PTBC in non uniform granular lumps. The advantages of PTBC in crystalline form as against using PTBC in the solid cast form are many and are as follows:

" It is not necessary to scoop out PTBC crystals using special tools as against PTBC in the cast form.

" PTBC in the cast form requires heating of the container in order to ensure smooth removal from the container. This step is eliminated when using PTBC crystals.

" PTBC crystals reduce the chance of skin irritation due to exposure.

TBC Non Uniform granular lumps. The above is a sample drawn randomly from our production lot. Actual size of the crystals vary. PTBC changes colour on exposure to air and light. This does not affect the chemical properties or effectiveness of TBC.

Packaging

Packaging of TBC depends on the type of grade ordered. We offer the following standard packaging:

"200 Kgs HM-HDPE (plastic) drums for Emulsion

"200 Kgs MS-Drums (steel) Epoxy lined for Emulsion

"1000 litres IBC for emulsion

"Plastic bags in 25 Kgs fibre drums for non-uniform crystalline solid.

Product Uses

P-Tert Butyl Catechol is a polymerisation inhibitor that is widely used in processing Styrene, Butadiene, and Vinyl Acetate monomers. Further P-Tert Butyl Catechol is used

"as a polymerisation inhibitor in the manufacture of polyester resins

" as a stabiliser of tin catalyst in the manufacture of polyurethane foam

" as a inhibitor in cross-linked polyester resins.

Product Handling and Storage

P-Tert Butyl Catechol is quite similar to Phenol in its potential dangers. Use the following procedures for handling and storing P-Tert Butyl Catechol.

1. Avoid contact with skin and eyes by wearing well fitted goggles, gloves and face shield.

2. Change and clean clothing regularly, especially if contaminated by P-Tert Butyl Catechol.

3. In case of skin contact, wash with large amounts of soap and water for 15 minutes or more.

4. In case of eye contact wash with water for 15 minutes or more.

5. Provide adequate ventilation.

6. Obtain first aid immediately in case of contact.

7. Some individuals maybe hypersensitive to P-Tert Butyl Catechol.This is displayed by excessive skin irritation on very slight exposure. Such individuals should not be allowed to come in contact with P-Tert Butyl Catechol.

P-Tert Butyl Catechol has a shelf life of several years if stored correctly. P-Tert Butyl Catechol should be stored in a closed container made of HM-HDPE without exposure to air or moisture. P-Tert Butyl Catechol is hygroscopic, absorbing moisture from the air. Further, P-Tert Butyl Catechol changes colour from white to tan on exposure to air. The colour change is normal and expected. It does not affect the chemical properties or effectiveness of TBC.

Prolonged contact to P-Tert Butyl Catechol with Nickel and Iron will cause it to darken. Exposure to Iron or Nickel will affect the chemical properties of TBC. If TBC comes in contact with an alkali (Caustic Soda) even in small quantities, TBC will immediately react to form a phenate and lose its effectiveness. Hence users should be extra careful to ensure that there is no presence of any caustic soda or similar material in their storage tanks or pipelines while using TBC.

When using PTBC crystals, please ensure that the once the bag is opened, it should be stored in an airtight container.
