What's the difference between thionol and thionyl?
Thionol
Definition:
(n.) A red or violet dyestuff having a greenish metallic luster. It is produced artificially, by the chemical dehydration of thionine, as a brown amorphous powder.
Example Sentences:

(2) In neonatal animals, phenothiazine, with up to 12% of the sulfoxide together with traces of leucophenothiazone, phenothiazone, and thionol was excreted in urine.
Thionyl
Definition:
(n.) The hypothetical radical SO, regarded as an essential constituent of certain sulphurous compounds; as, thionyl chloride.
Example Sentences:

(3) The reaction between 1,9-phenazinedicarboxylic acid and thionyl chloride in the presence of dimethylformamide unexpectedly gave 4-chloro-1,9-phenazinedicarbonyl chloride.
(4) Treatment of the 2,3,4,2',3',4'-hexa- O-acetyl-alpha, alpha-trehalosuronic acid 16 with thionyl chloride followed by diazomethane gave a crystalline bisdiazoketone which, however, failed to produce the expected bis(heptosiduronic acid) on attempted Wolff rearrangement.
(5) One of these analogues, dimethylthionocarbamylcholine (DMTC-Ch), has the ester carbonyl oxygen replaced by a thionyl sulfur.
(6) Hydrolysis of 3 gave the corresponding acids 4 which on treatment with thionyl chloride followed by ammonia afforded the corresponding carboxamides 5.
(7) The oxathiadiazoles 6 were synthesized by a two-step sequence: treatment of a substituted acetonitrile (4) with hydroxylamine to give the corresponding amidoxime (5) and cyclization with thionyl chloride to yield 6.
(8) Preservatives were isolated by extraction of the samples with diethyl ether in acidic media, and then converted into methyl esters with thionyl chloride.
(9) This route involves displacement reactions on the allylic chloride (4h) prepared from 4a by reaction with thionyl chloride.
(10) The reaction of 3beta, 5beta-dihydroxy cholestanes with thionyl chloride is shown to yield cyclicsulfite esters containing boat heterocyclic rings with the S=O oxygen axial or equatorial, depending upon the mode of formation.
(11) Treatment of these compounds with hydriodic acid at 95 degrees and then with thionyl chloride gave rise to the formation of the corresponding bis-(beta-chloroethyl)amino derivatives.
(12) A second generation, implantable drug administration device (DAD, Medtronic, Inc, Minneapolis) which contains a 20-mL drug reservoir, a lithium-thionyl-chloride battery, a peristaltic roller pump, a microprocessor circuit, and an acoustic transducer has entered clinical trials.
(13) (Ethoxycarbonyl)phosphonic dichloride (3) was synthesized by chlorination of bis(trimethylsilyl) (ethoxycarbonyl)phosphonate with thionyl chloride.
(14) GC analysis of the reaction product of 5alpha-cholestan-6alpha-ol and thionyl chloride showed the formation of 6alpha-chloro-5alpha-cholestane, cholest-5-ene, 5-chloro-5alpha-cholestane, and traces of four unidentified substances, whilst the GC-MS system furnished visual reproductions of the gas chromatograms, but again failed to yield corresponding mass chromatograms.
(15) Azulenes reacted unexpectedly and readily with thionyl chloride to give sulfonic acid chlorides and bisthioethers.
(16) Chlorination of 4a with thionyl chloride followed by alpha-bromination with bromine yielded 2-bromo-3,3-dimethyl[1-14C]-butyryl halide (5a), which was subsequently condensed with alpha, alpha-dimethylbenzylamine (6a) to afford [carbonyl-14C]bromobutide (1a).
(17) We have synthesized this derivative from the reaction of thionyl chloride with O6-(2-hydroxyethyl)guanine, and have found that it decomposes to 1-(2-hydroxyethyl)guanine through an intermediate, presumably 1,O6-ethanoguanine.
(18) Diols II, synthesized from I with NaBH4, were cyclized to five-membered cyclic compounds III by using N,N'-carbonyldiimidazole, thionyl chloride, N,N'-(thiocarbonyl)diimidazole, bromochloromethane, 2,2-dimethoxypropane, and cyclohexanone dimethyl ketal.
(19) The acetylated derivative of the trihydroxy C25 bile acid was then converted into 3 alpha,6 beta,7 alpha,26-tetraacetoxy-27-nor-5 beta-cholestan-25-one by successive treatment with thionyl chloride, diazomethane, and acetic acid.
