Rubber Auxiliaries N-Cyclohexyl-2-benzothiazolyl

N-Cyclohexyl-2-benzothiazolyl subsulfonamide (CBT for short) is an organic compound with the following properties:
1. Appearance: CBT is a solid in the form of white or off-white crystals or powder.
2. Solubility: CBT dissolves well in some common organic solvents (e.g. toluene, dimethyl sulfoxide and tetrahydrofuran, etc.).
3. Melting point: The melting point of CBT ranges from 140-143℃.
4. Stability: CBT is relatively stable and can be stored for long periods of time under conventional storage conditions.
The main use of CBT is as a drug intermediate. It can be used to synthesise a wide range of biologically active compounds, such as antibacterial drugs, antiviral drugs and antitumour drugs. Its unique structure and chemical properties give CBT the potential for a wide range of applications in medicinal chemistry.
The preparation of CBT can be carried out by a two-step reaction. First, cyclohexyl sulfate chloride undergoes a substitution reaction with 2-aminobenzothiazole to obtain N-cyclohexyl-2-benzothiazole sulfuryl chloride. Then, the sulfuryl chloride is reacted with an amine to produce N-cyclohexyl-2-benzothiazolyl subsulfonamide.
The following safety information is important to keep in mind when using and handling CBT:
1. CBT may be irritating to the skin, eyes and respiratory tract and contact should be made to avoid direct exposure.
2. necessary personal protective measures should be taken when handling CBT, including the wearing of protective gloves, glasses and masks.
3. Solutions of CBT should be handled in a well-ventilated area and inhalation of its dust or vapour should be avoided as far as possible.
4. When using CBT, it should be carried out in strict accordance with the operating procedures and follow the relevant safety instructions.
5. CBT needs to be protected from heat, humidity and direct sunlight during storage and transport.

Product Properties: Off-white powder (granule), slightly odour, non-toxic. Specific gravity 1.31-1.34, melting point over 98℃, easily soluble in benzene, toluene, chloroform, carbon disulfide, methylene chloride, acetone, ethyl acetate, not easily soluble in ethanol, insoluble in water, dilute acid, dilute alkali and gasoline.
Product Usage: CZ is a kind of highly active after-effect accelerator, with excellent anti-scorch performance, safe processing and short vulcanisation time. It has strong promotion effect when the vulcanisation temperature is above 138℃. It is often combined with WILLING TMTD, WILLING DPG or other alkaline accelerators as the second accelerator. Alkaline accelerators such as thiuram and dithiocarbamates can enhance its activity. Mainly used in the manufacture of tyres, hoses, rubber shoes, cables and other industrial Rubber Products.
Packing: 25kg plastic woven bag, paper-plastic composite bag, kraft paper bag, or plastic woven bag.
Storage: It should be stored in a cool, dry and well-ventilated place in a single layer. Packed products should be kept out of direct sunlight, overlapping stacking will cause abnormal compression or particle breakage. High humidity or high temperature will cause product decomposition. Valid for 1 year.
Description: This product can be made into superfine powder according to customers' requirements.

Company information

The company's main import and export products include

(1)Water Treatment:Physical methods also include precipitation, is to let the impurities of smaller specific gravity float on the surface of the water to fish out, or the impurities of larger specific gravity precipitation in the lower, and then obtain. Chemical method is to use a variety of chemicals in the water impurities into less harmful substances, or impurities concentrated, the longest history of chemical treatment methods should be considered to be added to the water with alum, the collection of impurities in the water, the volume becomes larger, it can be used for filtration, the removal of impurities.

(2)Catalysts And Auxiliaries：The catalyst is the active component that really acts as a catalyst and reduces the activation energy of the reaction. The additives, on the other hand, are auxiliary components, either structural additives or electronic additives, which can improve the stability of the catalyst, while the electronic additives can modulate the electronic properties of the catalyst.Our main Catalysts and Additives products include Plastic Additives、Water Treatment Agent.
