| fractional distillation | Distillation of a compound liquid at varying degrees of heat whereby the components of different boiling points are collected separately. (05 Mar 2000) |

| molecular distillation | Distillation in high vacuum, intended to make possible use of low temperatures to minimise damage to thermally labile molecules that would be decomposed by boiling at higher temperatures. (05 Mar 2000) |
|---|---|
| destructive distillation | Submission of an organic substance to heat in a closed vessel so that oxygen is absent and combustion prevented, with the objective of effecting its decomposition with release of volatile constituents and the formation of new substances. Synonym: destructive distillation. (05 Mar 2000) |
| distillation | <technique> A lab technique used to purify a substance, to remove a solvent (a liquid that a substance is dissolved in) from the substance, or to separate two or more components in a liquid mixture. Ideally, this is done by taking advantage of the fact that the different chemicals have different boiling points. The temperature is raised so the chemical with the lowest boiling point boils first, its vapor is shunted out of the flask and towards a different container, and then it is cooled so that it condenses back into a (more purified) liquid. The temperature can then be raised to boil the next chemical, etc., until only the chemical with the highest boiling point remains in the original container. (11 Jan 1998) |
| dry distillation | Submission of an organic substance to heat in a closed vessel so that oxygen is absent and combustion prevented, with the objective of effecting its decomposition with release of volatile constituents and the formation of new substances. Synonym: destructive distillation. (05 Mar 2000) |
| fractional | 1. Of or pertaining to fractions or a fraction; constituting a fraction; as, fractional numbers. 2. Relatively small; inconsiderable; insignificant; as, a fractional part of the population. <chemistry> Fractional crystallization, a process of distillation so conducted that a mixture of liquids, differing considerably from each other in their boiling points, can be separated into its constituents. Source: Websters Dictionary (01 Mar 1998) |
| fractional condensation | A lab technique used to separate the components of a vapor containing a mixture of substances. This is done by taking advantage of the fact that the different chemicals have different boiling points. The mixture undergoes repeated condensations, where the chemical with the highest boiling point condenses out of the vapor first and can be separated from the rest, then the chemical with the next highest boiling point condenses out, etc. (09 Oct 1997) |
| fractional dose | A definite fraction of a full dose; given repeatedly at short intervals so that the full dose is taken within a specified period, usually one day. Synonym: fractional dose. (05 Mar 2000) |
| fractional epidural anaesthesia | Insertion of a catheter into the lumbar or caudal epidural space for the repeated injection of local anaesthetic solutions as a means of prolonging duration of anaesthesia. Synonym: fractional epidural anaesthesia. (05 Mar 2000) |
| fractional spinal anaesthesia | Insertion of a catheter into the spinal subarachnoid space and leaving it in situ to permit serial intermittent injection of local anaesthetic solution for prolonged spinal anaesthesia. Synonym: fractional spinal anaesthesia. (05 Mar 2000) |
| fractional sterilization | Exposure to a temperature of 100°C (flowing steam) for a definite period, usually an hour, on each of several days; at each heating the developed bacteria are destroyed; spores, which are unaffected, germinate during the intervening periods and are subsequently destroyed. Synonym: discontinuous sterilization, intermittent sterilization, tyndallization. (05 Mar 2000) |

In the fractional steam distillation process, the essential oil is collected in batches over the distillation period during given time intervals. Ylang Ylang is a material in which the initial oil yield taken initially and is referred to as Ylang Ylang 1st. The next is referred to as Ylang Ylang 2nd, and thereafter Ylang Ylang 3rd. A blend of all the batches is referred to as Ylang Ylang Complete.
