Physical and chemical properties
Alcohols, C16-18
1.Appearance
Alcohols, C16-18 is solid white waxy flakes with faint characteristic odour at 20°C and 1013 hPa. and colorless liquid when melted.
2.Melting point
Using the EPI Suite Mpbwin (v.1.43) QSAR model, a Melting Point of 57.74 deg C was established according adapted Joback Method.
3.Boiling point
Using the EPI Suite Mpbwin (v.1.43) QSAR model, a Boiling Point of 330.79 deg C (estimated) was established.
4.Specific gravity
0.8
5.Vapour pressure
A QSAR method predicts the vapour pressure of this substance to be 0.00119 Pa at 25C.
6.Water solubility
0.072197 mg/l (calculated)
0.1495 mg/l (calculated)
Substance is predicted by QSAR method to be insoluble (0.072197 mg/l) with water.
Substance is predicted by QSAR method (EPI Suite v 4.1/WSKOW v1.42 ) to be slightly soluble ( 0.1495 mg/l) in water.
7.Partition co-efficient
A reliable QSAR method predicts a value for the partition co-efficient (logKow) of 6.73 for this substance.
8.Hydrolysis as a function of pH
As Alcohols, C16-18 is ready biodegradable a Hydrolysis study does not need to be conducted.
Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. This substance has no hydrolysable structural features and would be expected to be stable in respect of hydrolysis.
Alcohols have no hydrolysable groups and are therefore not susceptible to hydrolysis (Lyman, Reehl and Rosenblatt, 1990).
Oxidation would not be expected under normal environmental conditions.
9.Adsorption/desorption
The log of the adsorption coefficient (KOC) of Alcohols, C16-18 was estimated to be log KOC = 3.6682 which is equal to a KOC value of 4658 using the KOCWIN v2.00 QSAR method. Estimate from MCI.
The log of the adsorption coefficient (KOC) of Alcohols, C16-18 was estimated to be log KOC = 4.2362 which is equal to a KOC value of 17230 using the KOCWIN v2.00 QSAR method. Estimate from Log Kow.
10.Dissociation constant
A dissociation constant value of 15.76 was obtained using an accepted calculation method. The result is considered to be reliable.
11.Flammability
From the compositional description and the structural formula given, it can be concluded that this substance CAS 67762-27-0, (EINECS) 267-008-6 is not pyrophoric (will not ignite or emit flammable gases on contact with air, damp air, or water) nor does it exhibit the property of flammability (will not easily burn when ignited or contribute to the combustion of other materials). There are no functional groups or other structural alerts present that would support any concern that this substance should be classified as dangerous according to the criteria for evaluating flammability, which is furthermore confirmed by long term handling experience.
12. Flash point
A open-cup flash point value of >160ºC is reported in a collection of reliable data which has been subject to peer-review . The result is considered to be reliable.
13.Explosiveness
From the compositional description and the structural formula given, it can be concluded that this substance CAS 67762-27-0, (EINECS) 267-008-6 does not exhibit explosive properties (will not detonate or deflagrate, under conditions of excessive heating with or without confinement, impact, or friction to produce heat and or gas). There are no functional groups or other structural alerts associated with explosive properties or tendencies that would indicate that this substance will manifest explosive properties. Similarly, the calculated Oxygen Balance is less than -200 suggesting that testing need not be conducted and that a negative result can be predicted. Thus, this substance should not be classified as dangerous according to the criteria for explosivity, which is furthermore confirmed by long term handling experience.
14.Stability In Organic Solvent
From the compositional description and the structural formula given, it can be concluded that this substance CAS 67762-27-0, (EINECS) 267-008-6 is stable in organic solvents. There are no functional groups or other structural alerts present that would indicate that this substance should be reactive or give rise to any instability under routine storage conditions or testing conditions in general. This reality is furthermore confirmed by long term handling experience in addition to observations made during subsequent downstream formulating and blending operations where this substance is also observed to be very stable.
It should be noted that this substance is not completely soluble in some very polar low molecular weight organic solvents (egs. alcohols, esters, ketones, and ethers). However, this is not the result of substance instability, and no reactions between these solvents and the functional groups present in this substance would be expected.
15.Viscosity
The viscosity of Alcohols, C16-18 was determined according ASTM D 445. The viscosity was determined to be 3.9 mm²/s at 100 °C. The viscosity was determined to be 16 mm²/s at 49 °C and 10.8 mm²/s at 60 °C.
16.Decomposition products
Decomposition products may include the following materials: carbon dioxide, carbon monoxide
17.Autoignition temperature
From the compositional description, the structural formula given, it can be concluded that it is not necessary to evaluate the ignition temperature of this substance by either the Self- or Auto-Ignition testing criteria indicated in the TGD.
There are no functional groups or other structural alerts present that indicate that this substance would spontaneously ignite in air when exposed to a hot surface and thus should not be classified as dangerous with respect to this endpoint.
This empirical evaluation is furthermore confirmed by long term handling experience. The study is therefore considered scientifically unjustified.
Therefore testing for Auto flammabilitydoes not need to be performed.
18.Reactivity
Reacts with oxidizing agents. Reacts with bases. Reacts with strong acids.
19.Composition of commercial product
Alcohols, C16-18 is from the category of Long Chain aliphatic Alcohols within a carbon chain length range of C6-C22. The substance (C16-18 Alcohols CAS № 67762-27-0) comprises 100% linear (or unstated); <2% C14, >=90% C16 and 18 >5% C20.
20.Oxidizing properties
From the compositional description and the structural formula given, it can be concluded that this substance CAS 67762-27-0, (EINECS) 267-008-6 does not exhibit oxidizing properties (will not cause or contribute to the combustion of other materials by virtue of its own inherent oxidation or reduction potential). There are no functional groups or other structural alerts present that would indicate that this substance would promote oxidation and thus should not be classified as dangerous according to the criteria for evaluating oxidizing properties. Furthermore, this is confirmed by long term handling experience.
