Octadecyltrichlorosilane

Octadecyltrichlorosilane (ODTS or n-octadecyltrichlorosilane) is an organosilicon compound with the formula CH3(CH2)17SiCl3. A colorless liquid, it is used as a silanization agent to prepare hydrophobic stationary phase, for reversed-phase chromatography. It is also evaluated for forming self-assembled monolayers on silicon dioxide substrates. Its structural chemical formula is CH3(CH2)17SiCl3. It is flammable and hydrolyzes readily with release of hydrogen chloride. Dodecyltrichlorosilane, an ODTS analog with shorter alkyl chain, is used for the same purpose. ODTS-PVP films are used in organic-substrate LCD displays. Wikipedia

(7) Special Provisions (§172.102) ×Note: Special provisions may be very complex. The extracts are taken from 49 CFR §172.102. Please be careful with the information, as necessary, additional conditions may be applied that are not written here. Please check the original source and report bugs. A7 Steel packagings must be corrosion-resistant or have protection against corrosion. Browse special provision A7 B2 MC 300, MC 301, MC 302, MC 303, MC 305, and MC 306 and DOT 406 cargo tanks are not authorized. Browse special provision B2 B6 Packagings shall be made of steel. Browse special provision B6 N34 Aluminum construction materials are not authorized for any part of a packaging which is normally in contact with the hazardous material. Browse special provision N34 T10 see 49 CFR §172.102 TP2 a. The maximum degree of filling must not exceed the degree of filling determined by the following: Where: tr is the maximum mean bulk temperature during transport, tf is the temperature in degrees celsius of the liquid during filling, and α is the mean coefficient of cubical expansion of the liquid between the mean temperature of the liquid during filling (tf) and the maximum mean bulk temperature during transportation (tr) both in degrees celsius. b. For liquids transported under ambient conditions α may be calculated using the formula: Where: d15 and d50 are the densities (in units of mass per unit volume) of the liquid at 15 °C (59 °F) and 50 °C (122 °F), respectively. Browse special provision TP2 TP7 The vapor space must be purged of air by nitrogen or other means. Browse special provision TP7 TP13 Self-contained breathing apparatus must be provided when this hazardous material is transported by sea. Browse special provision TP13

(9) Quantity Limits (9A) Passenger aircraft/rail Forbidden (9B) Cargo aircraft only 30 L
(10) Vessel stowage (10A) Location C Stowage category “C” means the material must be stowed “on deck only” on a cargo vessel or on a passenger vessel. Source: 49 CFR §172.101(k) (10B) Other 40 Stow “clear of living quarters”. Source: 49 CFR §176.84

Segregation Chart for Load, Transport, Storage

In this table a statement is contained for each hazard class whether the loading, transport or storage with other hazard classes is allowed, is not permitted or is restricted. The table is based on U.S.-Code 49 CFR §177.848.

Note: In this segregation and separation chart are HazMat of hazard class 8 considered depending if there are liquid. Currently HazMat Tool is not able to to check if a HazMat is liquid or not. Therefore it is assumed as liquid. See PHMSA Interpretation #09-0252.
