What are the physical properties of paraffin?

What are the physical properties of paraffin?

Properties. Paraffin wax is mostly found as a white, odorless, tasteless, waxy solid, with a typical melting point between about 46 and 68 °C (115 and 154 °F), and a density of around 900 kg/m3. It is insoluble in water, but soluble in ether, benzene, and certain esters.

What type of compound is paraffin?

alkanes
Paraffins, also known as alkanes, are saturated compounds that have the general formula CnH2n+2, where n is the number of carbon atoms. The simplest alkane is methane (CH4), which is also represented as C1. Normal paraffins (n-paraffins or n-alkanes) are unbranched straight-chain molecules.

What are the physical and chemical properties of the candle?

For a candle, its physical properties may refer to its color which typically is white. The chemical property of a candle includes its combustibility which is defined as its capacity to be combusted producing heat, light, carbon dioxide, and water in the presence of oxygen.

Why the melted paraffin is allowed?

A container of melted paraffin wax is allowed to stand at room temperature until the wax solidifies. Heat flows from melted paraffin wax to the environment.As heat is lost it is exothermic.

Is paraffin a aliphatic compound?

2.14. Paraffins – alkanes (CnH2n+2) – are saturated aliphatic hydrocarbons and consist of (CH2)n chains.

Is decompose a physical or chemical property?

One type of matter is changed into something different. We will consider some examples of chemical change: the decomposition (breaking down) of hydrogen peroxide and the synthesis (forming) of water and of iron sulfide.

Is flammability a physical or chemical property?

Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust.

Why is paraffin bad?

Most candles today are made of paraffin wax which creates highly toxic benzene and toluene when burned (both are known carcinogens). In fact, the toxins released from paraffin candles are the same as those found in diesel fuel fumes and are linked to asthma and lung cancer.

What are the physical properties of liquid paraffin?

Physical Properties. Liquid paraffin is an oily, transparent, colorless liquid. At room temperature it is odorless and tasteless. However, when heated it does have a slightly unpleasant petroleum smell. It does not dissolve in water, glycerol or cold ethanol. It does dissolve in benzene, ether, chloroform and hot ethanol.

What is the melting point of paraffin wax?

The melting point ranges from 47 to 65°C (Lewis 2002). The flash point equals 390°F or 198°C (Lewis 2002). The autoignition temperature is reached at 473°F or 245°C (Lewis, 2002). The paraffin wax has a molar mass equal to 785 g/mol and a C/O ratio of 18.8/1 (Krupa and Luyt 2001).

What are the physical properties of beeswax and paraffin?

The density varies between 0.88 and 0.94 g/cm3 (Lewis 2002; Krupa and Luyt 2001). The melting point ranges from 47 to 65°C (Lewis 2002). The flash point equals 390°F or 198°C (Lewis 2002). The autoignition temperature is reached at 473°F or 245°C (Lewis, 2002).

What’s the difference between petroleum jelly and paraffin wax?

It is distinguished by its solid state at ordinary temperatures (25°C, 77°F) and low viscosity (35–45 SUS at 99°C, 210°F) when melted. However, in contrast to petroleum wax, petrolatum ( petroleum jelly ), although solid at ordinary temperatures, does in fact contain both solid and liquid hydrocarbons.
